PREFACE

This is the eighth Technical Note in a series of publications containing

selected values of chemical thermodynamic properties of inorganic compounds.

This Technical Note essentially completes the revision of National Bureau of

Standards Circular 500, Selected Values of Chemical Thermodynamic Properties,

by F. D. Rossini, D. D. Wagman, W. H. Evans, S. Levine, and I. Jaffe. This

volume covers the compounds of the elements uranium, protactinium, thorium,

actinium, lithium, sodium, potassium, rubidium, cesium, and francium. In addition there is an appendix in which are listed revisions to a number of the

values given in the preceding Technical Notes in this series (NBS Technical

Notes 270-3 through 270-7). These revisions include data for some additional

compounds as well as updates and corrections for errors that have been brought

to our attention.

The values for the compounds of thorium, sodium, potassium, and rubidium

given in this Technical Note supersede those given in the earlier reports,

NBSIR 76-1034, Chemical Thermodynamic Properties of Compounds of Sodium, Potassium, and Rubidium: An Interim Tabulation of Selected Values, and NBSIR 77-1300,

A Computer-Assisted Evaluation of the Thermochemical Data of the Compounds of

Thorium. The latter report utilizes auxiliary data different from that used

in this series of Technical Notes.

A combined volume containing all the material published in the Technical

Note 270 series is being prepared for publication. This volume will be in SI units.

The continued encouragement and assistance of the Office of Standard Ref- erence Data of the National Bureau of Standards is gratefully acknowledged.

SELECTED VALUES OF CHEMICAL THERMODYNAMIC PROPERTIES

by

Donald D. W a g m a n , WiLLiam H. Evans, Vivian B. Parker,

Richard H. Schumm, and RaLph L. Nuttall

INTRODUCTION

Substances and Properties Included in the Tables

The tables contain values where known of the enthalpy and Gibb

energy of formation, enthalpy, entropy and heat capacity at 298.15 K (25 C), and the enthalpy of formation at K, for all inorganic

substances and organic molecules containing not more than two carbon

atoms. In some instances such as for metal-organic compounds, data

are given for substances in which each organic radical contains one

or two carbon atoms.

No values are given in these tables for metal alloys or other

solid solutions, fused salts, or for substances of undefined chemical

composi ti on

.

Physical States

The physical state of each substance is indicated in the column

headed "State" as crystalline solid (c), liquid [L), glassy or amorphous (amorp), or gaseous (g). For solutions, the physical state

is that normal for the indicated solvent at 298.15 K. Isomeric

substances or various crystalline modifications of a given

substance are designated by a number following the letter designation, as c2, g2, etc.

Definition of Symbols

The symbols used in these tables are defined as follows:

P = pressure; V = voLume; T = absolute temperature; S = entropy;

H = enthalpy (heat content); G = H - TS = Gibbs energy (formerly

the free energy); C = (dH/dT) = heat capacity at constant

pressure.

" "

vn
Conventions Regarding Pure Substances

The values of the thermodynamic properties of the pure substances

given in these tables are for the substances in their standard states

o (indicated by the superscript on the thermodynamic symbol). These

standard states are defined as follows:

For a pure solid or liquid, the standard state is the substance in

the condensed phase under a pressure of one atmosphere.*

For a gas the standard state is the hypothetical ideal gas at unit

fugacity, in which state the enthalpy is that of the real gas at the same temperature and zero pressure.

The values of AHf and AGf given in the tables represent

the change in the appropriate thermodynamic quantity when one gram-formula weight of the substance in its standard state is formed

isothermally at the indicated temperature from the elements, each in

its appropriate standard reference state. The standard reference

state at 298.15 K for each element except phosphorus has been chosen

to be the standard state that is t h

e

rmody nam i ca I I y stable at that

temperature and one atmosphere pressure. For phosphorus the standard

reference state is the crystalline white form; the more stable forms

have not been well characterized thermochemically. The same reference

states have been maintained for the elements at K except for the

liquid elements bromine and mercury, for which the reference states have

been chosen as the stable crystalline forms. The standard reference

statesooare indicated-in the tables by the fact that the values of

AHf and :Gf are exactly zero and the Letter "s" follows the

physical state designation.

The value of H° „„ - H° represents the enthalpy difference 298

for the given substance between 298.15 K and K. If the indicated

standard state at 298.15 K is the gas, the corresponding state

at K is the hypothetical ideal gas; if the state at 298.15 K is

solid or Liquid, the corresponding state at K is the thermodynamically

stabLe crystalline solid, unless otherwise specifically indicated.

The values of S represent the virtual or "thermal" entropy of

the substance in the standard state at 298.15 K, omitting contributions

from nuclear spins. Isotope mixing effects, etc., are also excluded

except in the case of the hydrogen-deuterium system. Where data have

been available only for a particular isotope, they have been corrected

when possible to the normal isotopic composition.

The values of the enthalpies of formation of gaseous ionic species

are computed on the convention that the value of AHf for the electron is zero. Conversions between and 298.15

and non-ionized molecules are the same

* One standard atmosphere equals 101325 pascal.
Conventions Regarding Solutions

For all dissolved substances the composition of the solvent

is indicated foLLowing the chemical formula of the solute. In

most instances the number of moles of solvent associated with one mole of solute is stated explicitly. In some cases the concentration

of the solute cannot be specified. For aqueous solutions this is

indicated in the State column by "au" (aqueous, unspecified). Such

solutions may be assumed to be "dilute".

The standard state for a strong electrolyte in aqueous solution

is the ideal solution at unit mean molality (unit activity). For a no n- dissociating solute in aqueous solution the standard state is the

ideal solution at unit molality. These states are indicated in

State column by the designations "a" and "ao" respectively. In

previous tables of this Series these solutions were designated

"std. state, m=1" and "undissoc., std. state, m=1".

the

as

For non-aqueous solutions the standard state for the solute may

be the ideal solution at unit mol fraction of solute or at unit

molality. These standard states are designated by adding "X" or "S" respectively to the formula of the solvent. Previously these

have been described as "std. state, x_ =1" or "std. state, m=1".

Solutions of unspecified concentration are designated by adding "U"

to the formula of the solvent.

The value of AHf for a solute in its standard state is equal

to the apparent molal enthalpy of formation of the substance in the

infinitely dilute solution, since the enthalpy of dilution of an ideal solution is zero. At this dilution the partial molal enthalpy

is equal to the apparent moLal quantity. At concentrations other than

the standard state, the value of AHf represents the apparent

enthalpy of the reaction of formation of the solution from the

elements comprising the solute, each in its standard reference state,

and the appropriate total number of moles of solvent. In this

representation the value of AHf for the solvent is not required.

The experimental value for an enthalpy of dilution is obtained

directLy as the difference between the two values of AHf at the

corresponding concentrations. At finite concentrations the partial

molal enthalpy of formation differs from the apparent enthalpy. In

some instences the partial molal enthalpy of formation is given

in the Tables. In this case the concentration designation is

preceded by "D:".

The values for the thermodynamic properties for an individual

ion in aqueous solution are for that undissoc iated ion in the

standard state and are based on the convention that AHf , AGf , S , and Cp for H (a) are zero. The properties of the neutral

strong electrolyte in aqueous solution in the standard state are equal to the sum of these values for the appropriate number of

ions assumed to constitute the molecule of the given electrolyte.

By adopting the above convention with respect to H (a), it follows

that for an individual ionic species the G-H-S relation becomes

- T( ASf° + (n/2)S°(H

2 (gs)))

with n = the algebraic value of the ionic charge. For neutral eLectroAGf = AHf

= the algebi

lytes and gaseous ions the normal consistency relation holds (see below)

IX
Unit of Energy and Fundamental Constants

Alt of the energy values given in these tables are expressed in

terms of the th

e

rmochem i ca L calorie. This unit, defined as equal to

4.1840 joules, has been generally accepted for presentation of chemical

thermodynamic data. Values reported in other units have been

converted to calories by means of the conversion factors for molecular

energy given in Table A.

The following values of the fundemental physical constants have been

used in these calculations:

R = gas constant = 8.3143 + 0.0012 J/deg mol = 1.98717 + 0.00029

cal/deg mol

F = Faraday constant = 96487.0 +1.6 coulombs/mol

= 23060.9 + 0.4 cal/V equivalent

U C 273 .15 K These constants are consistent with those given in the Table of Physical

Constants, recommended by the National Academy of Sciences - National

Research Council [1]. The formula weights Listed in the tables have been

calculated for the empirical molecular formula given in the Formula and

Description column.

CODATA Task Group on Fundamental Constants, C0DATA Bulletin 11,

December 1973.
Internal Consistency of the Tables

The various aspects of internal consistency are specified below

1. Subsidiary and auxiliary quantities used.

2 . Physical and thermodynamic relationships for the tabulated

properties of a substance.

The tabulated values of the properties of a substance satisfy aLL

the known physical and thermodynamic relationships among these properties

The quantities AHf°, AGf° f and S° at 298.15 K satisfy the reLation

(within the assumed uncertainty]

AGf° = AHf° - T ASf°

In addition, the calculated value of any thermodynamic quantity for a reaction is independent of the path chosen for the evaluation.

However, in a few specific cases the G-H-S relation has been

relaxed, as explained below.

3. Effect of newer data on values selected and fixed earlier.

In an evaluation as comprehensive and Lengthy as this Technical

Note Series, in which a sequential method is used [2], values previously

selected are considered fixed and are then treated as auxiliary data in

subsequent calculations. This maintains the internal consistency necessary

to retrieve the experimental data (within the expected uncertainty) and

to predict the thermochemical properties of processes not directly

measured.

Newer data on some species have become available after their values

were fixed and used in subsequent calculations. It is not possibLe to

incorporate these newer data into the tables without a detailed analysis

of the effect of this change,

ficant errors in

processes may result from the introduction of such data. The user is

advised not to make these substitutions.

Sums and Least Squares Approach to the Evaluation of Thermodynamic

Data Networks, NBSIR 76-1147 (1976).

XI
In some cases changes can be and have been made; we are certain that

the values in question and all values dependent on them can be changed,

since only a_limited number of compounds are affected. Examples of these

are the Cl0 o [a] and BrO [a] ions, for which new values are listed

in the Appendix. New values for substances dependent on these ions are

also given there.

In other cases, as for F [a] and I [a], for which new data indicate

o significantly different values of AHf [3], such changes can not be

readily made, as they are "key substances" involved in many sets of

reactions used throughout the tables. A major revision of many values

would be required.

In some specific cases the G-H-S relationship has been relaxed, so that AGf [c] does not equal AHf [c] - T ASf [c] within the expected

uncertainty. They are designated in the tables by the statement:

G-H-S constraint has been relaxed; see Introduction.

These instances are limited to some of the alkali metal salts of I [a],

-2 -2

SO. [a], and C0_ [a]. Newer data on the entropies of solution and

Third Law entropies of a number of salts have Led to significantly

different values of the entropies of these ions from those reported

in TN 270-3 and used throughout these tables. In order to retain the

basic principle of these tables insofar as possible, namely that the

values in the tables should yield "best" values for thermodynamic processes,

we have selected values of AHf and AGf for the alkali metal salts

such that the "best" values of AH and AG for the ideal solution

process are maintained. The values of S for the salts are selected from

measurements independent of the solution process. In these cases the

following thermodynamic relation:

AS [solution] = [AH [solution] - AG [ so I ut i on ] ] /T

will hold for the ideal solution process but the following relation

will not be

Arrangement of the Tables

The compounds in the tables are entered according to the Standard

Order of Arrangement (see Figure 1], by the principle of latest

position. In this scheme a compound is listed under the element

occurring latest in the list. Within a given element-table will be

found all of the compounds of that element with elements occurring

earlier in the list; the arrangement within the table follows the

same ordering (water of hydration is neglected). An exception occurs

in the carbon table (Table 23), which is divided into subgroups

consisting of all compounds with one carbon atom, then all with two

carbon atoms, etc.

NBS TECHNICAL PUBLICATIONS

PERIODICALS

JOURNAL OF RESEARCH—The Journal of Research of the National Bureau of Standards reports NBS research and develop- ment in those disciplines of the physical and engineering sciences in which the Bureau is active. These include physics, chemistry,

engineering, mathematics, and computer sciences. Papers cover a broad range of subjects, with major emphasis on measurement

methodology and the basic technology underlying standardization. Also included from time to time are survey articles on topics

closely related to the Bureau's technical and scientific programs. As a special service to subscribers each issue contains complete

citations to all recent Bureau publications in both NBS and non- NBS media. Issued six times a year. Annual subscription: domestic

$13: foreign $16.25. Single copy, $3 domestic; $3.75 foreign. NOTE: The Journal was formerly published in two sections: Section A "Physics and Chemistry" and Section B "Mathematical

Sciences." DIMENSIONS/NBS—This monthly magazine is published to in- form scientists, engineers, business and industry leaders, teachers, students, and consumers of the latest advances in science and

technology, with primary emphasis on work at NBS. The magazine

highlights and reviews such issues as energy research, fire protection, building technology, metric conversion, pollution abatement,

health and safety, and consumer product performance. In addition, it reports the results of Bureau programs in measurement

standards and techniques, properties of matter and materials, engineering standards and services, instrumentation, and

automatic data processing. Annual subscription: domestic $11; foreign $13.75. NONPERIODICALS

Monographs—Major contributions to the technical literature on

various subjects related to the Bureau's scientific and technical activities. Handbooks—Recommended codes of engineering and industrial practice (including safety codes) developed in cooperation with in- terested industries, professional organizations, and regulatory

bodies. Special Publications—Include proceedings of conferences sponsored by NBS, NBS annual reports, and other special publications

appropriate to this grouping such as wall charts, pocket cards, and

bibliographies.

Applied Mathematics Series—Mathematical tables, manuals, and

studies of special interest to physicists, engineers, chemists,

biologists, mathematicians, computer programmers, and others engaged in scientific and technical work.

National Standard Reference Data Series—Provides quantitative data on the physical and chemical properties of materials, compiled from the world's literature and critically evaluated. Developed under a worldwide program coordinated by NBS under

the authority of the National Standard Data Act (Public Law

90-396).

NOTE: The principal publication outlet for the foregoing data is the Journal of Physical and Chemical Reference Data (JPCRD)

published quarterly for NBS by the American Chemical Society

(ACS) and the American Institute of Physics (AIP). Subscriptions,

reprints, and supplements available from ACS, 1 155 Sixteenth St., NW, Washington, DC 20056.

Building Science Series—Disseminates technical information developed at the Bureau on building materials, components,

systems, and whole structures. The series presents research results,

test methods, and performance criteria related to the structural and

environmental functions and the durability and safety characteristics of building elements and systems.

Technical Notes—Studies or reports which are complete in themselves but restrictive in their treatment of a subject. Analogous to monographs but not so comprehensive in scope or definitive in treatment of the subject area. Often serve as a vehicle for final reports of work performed at NBS under the sponsorship of other government agencies.

Voluntary Product Standards—Developed under procedures

published by the Department of Commerce in Part 10, Title 15, of

the Code of Federal Regulations. The standards establish nationally recognized requirements for products, and provide all concerned interests with a basis for common understanding of the

characteristics of the products. NBS administers this program as a supplement to the activities of the private sector standardizing

organizations. Consumer Information Series—Practical information, based on NBS research and experience, covering areas of interest to the con- sumer. Easily understandable language and illustrations provide

useful background knowledge for shopping in today's tech- nological marketplace. Order the above NBS publications from: Superintendent of Documents, Government Printing Office, Washington, DC 20402. Order the following NBS publications—FIPS and NBSIR's—from

the National Technical Information Services, Springfield, VA 22161

.

Federal Information Processing Standards Publications (FIPS

PUB)—Publications in this series collectively constitute the Federal Information Processing Standards Register. The Register

serves as the official source of information in the Federal Govern- ment regarding standards issued by NBS pursuant to the Federal Property and Administrative Services Act of 1949 as amended,

Public Law 89-306 (79 Stat. 1127), and as implemented by Executive Order 11717 (38 FR 12315, dated May 11, 1973) and Part 6 of Title 15 CFR (Code of Federal Regulations).

NBS Interagency Reports (NBSIR)—A special series of interim or

final reports on work performed by NBS for outside sponsors

(both government and non-government). In general, initial dis- tribution is handled by the sponsor; public distribution is by the National Technical Information Services, Springfield, VA 22161,

in paper copy or microfiche form.
