The CRC (68ed.) gives the solubility of silver oxalate as 3.39 X 10-3 g to
100mL water.  The Ksp is given as 5.40 X 10-12.  This gives a theoretical
solubility of 5.3 X 10-3 g to 100mL water.  (If I did my "back-of-the-envelope"
calculations correctly.)

>More on silver nitride (which apparently forms when many silver compounds

If one adds ammonia to a suspension of silver(I) oxide in basic solution, an
explosive compound known as "Bertholett's Silver" or "Fulminating Silver" is
formed.  I don't have a molecular formula, but the source of this info
references "F. Raschig.  _Annals_Of_Chemistry_. 233, 93 (1886)".  It seems
that compounds like this have been around for a while.  I wasn't able to
locate this article.

>I can't believe no one here knows anyone who has been maimed by this
>stuff.  Happens accidentally in photo labs (not developing labs) occaisonally.

This was how I first discovered fulminating silver.  I was preparing silver
oxide for an experiment from silver nitrate and sodium hydroxide.  Some of the
oxide was stuck to the inside of the flask I had prepared it in, so I figured
I'd dissolve it with a good silver solvent-- ammonia.  I let it sit and stir
while I went across the lab to centrifuge my silver oxide.  Good thing, too.
After about 5-10 minutes the flask blew up.

Expected explosions are fun.  Unexpected explosions are not.  But both my
advisor and myself learned something from that day...

The way I see it, there is no possible way for a lighter to explode.
They contain butane, C4H10 I belive, no oxygen, no combustion, and the
last time I cheched butane's not a high explosive.

A Chemical Kiloton Experiment
at the Nevada Test Site

The Lawrence Livermore National Laboratory (LLNL) will conduct a large
chemical explosion (CE) called the Chemical Kiloton Experiment (CKE) in the
Rainier Mesa area of the Nevada Test site. The explosion will involve a 30/70
Emulsion-to-ANFO blend of 1,147,000. kg (2,536,000 lb) to supply 1 kt, and is
scheduled to occur approximately January 29, 1993.  It will be heavily
instrumented with close-in free-field, surface seismic and regional seismic
measurements. The CKE is located near several DNA sponsored nuclear
explosions (NEs) and will provide a unique opportunity for fundamental
studies such as explosion phenomenology (e.g., CE/NE equivalence), scaling
with CEs and NEs, and integration of multiple monitoring methods. This
experiment will also address some critical proliferation monitoring problems
such as CE masking of NEs, CEs as false alarms, CEs for regional calibration
and on-site inspection.

Participating organizations include LLNL, Sandia National Laboratory, Los
Alamos National Laboratory, Phillips Laboratory, the University of Arizona
and the University of Nevada, Reno.  Other technical organizations are
welcome to field recorders, analyze the results and contribute data to an
integrated data base.  Those who are interested in more details regarding this
experiment should contact Don Larson of LLNL at 510-423-5162 or Fax 510-
423-4077.  A meeting to discuss the CKE is planned during the Annual AGU
Meeting in San Francisco. For those interested in more detail about the
experiment, please check the AGU announcement bulletin board at the
convention center for time and location.

The data from this experiment will be available via an integrated data base
which is being coordinated by Eileen Vergino of LLNL. Questions regarding
the data base should be directed to Eileen Vergino, 510-422-3907, Fax 510-423-
4077 or E-mail verginoes@llnl.gov.

fog juice is basically just glycerine with some added scent.  So,
what does glycerine give off when decomposed by heat?

Glycerin turns into acrolein when decomposed by heat, which is 
intensely irritating.  (It's what stings your eyes when fat gets
overheated.)  I'd hate to think of anything more aggrssive than
mechanical atomization wrt glycerin -- sound like a recipe for

ARRRGH!    :)

This is _exactly_ what I was asking about in my original post.

So what *are* these compounds that sensitize ANFO to the point where it
can be detonated with a blasting cap????

Or is that information too sensitive (heh) to be released to those, like
me, who would use it idly and most likely blow themselves to tiny little
bits?

I doubt if the lighter exploded. I would suspect that it allowed
the butane to leak out - forming a FAE. That would explode when
exposed to flame.

The result is the same. The moral is, always wear a leather welding

I believe the melting point of NaCl is around 3000 degrees.  It also helps
to have a dehumidifier running, especially if you are somewhere humid.  I
beleieve the Cl forms Cl2 gas (very poisonous-smells bad too).

Cl is very reactive and forms Cl2 quickly - in this state, it is still
quite reactive and thus poisonous. It is a greenish yellow gas, heavier than
the air. Hydrogen and Chlorine mixed together and exposed to light (especially
sunlight) has been know to detonate, forming Hydrogen Chloride. HCl mixed
with water is HydroChloric Acid (aka Muriatic Acid in your local hardware
store).

Cl itself is one the most reactive substances known, second only to Fluorine.
They all belong to the halogen family and include Bromine (a brown gas),
Iodine (dark crystals with a low melting point).
