Talk:Boric acid

message: "Now name-brand Silly Putty also contains significant amounts of elemental silicon (silicon binds to the silicone and allows the material to bounce 20% higher)."
Does anyone have a source for this?  Presumably a gray, metallic powder would be visible in the Silly Putty if silicon was present.  Also, elemental silicon is protected by a surface oxide layer, and would probably not bind to the silicone.  Even if it did, it seems unlikely that it would result in a higher bounce.
The same statement is repeated on the Silly Putty page, however, the formula listed there gives no mention of elemental silicon.  Unless someone can back up this statement, I will remove it from both articles shortly.

message: Boric acid is popularly used among fire jugglers and fire spinners dissolved in methanol to give a deep green flame.
I've added in a reference for this, from a Home of Poi article; Home of Poi is linked from the Poi (juggling) page, as "one of the largest and most influential poi communities in the world".

Boric acid poisoning, therefore, may induce riboflavin deficiency." Is that it? If so, I propose to remove the title from "Further reading", and the tag calling for the material to be included.  --Old Moonraker (talk) 20:40, 8 August 2008 (UTC)

message: I think a new section, or maybe a new page should be written about this. An amount of boric acid found in the house of one of the terrorists involved in the bombings suppossedly linked him to ETA. That wasn't considered important during the trial, and some think this information has been dismissed on purpose to hide connections between Al-Qaeda, ETA and even the current goverment. (This is thought by die-hard rightists who support Aznar's goverment and consider that 11-M was some sort of coup)
There's already a page about it in Spanish, but not in English, as far as I know.

thread_title:  ECHA Classification 

message: This article claims:
	'Boric acid, mixed with borax (sodium tetraborate decahydrate)
at the weight ratio of 4:5, is highly soluble in water' 
The article which it references says:
	 'the solution prepared by dissolving 20 g of boric acid and
25 g of borax into 100 g of hot water over 80 °C did not recrystallize
at 20 °C.'
and:
	'It should be noted that the mixture of boric acid and borax
does not dissolve into water at room temperature to the level of the
highly concentrated solution. This is considered to be due to the
problem of kinetics.'
	In other words one can't mix them 4:5 with room temperature
water and have them go into solution.  The person who wants to make
this solution needs this information.  The article isn't in the public
domain: one must either pay for it, have a subscription to the
journal, or go to a institution which has a subscription (what I did).

thread_title:  How one makes a solution of borax & boric acid with a high solubility 

message: Some mattresses are treated with boric acid powder in order to meet flame retardant regulations. This of course raises health concerns, but from what I understand boric acid is one of the least toxic 'treatments' available (As opposed to synthetic chlorinated and brominated chemicals). I didn't look for solid references, but I hope someone is inspired to do so, and add this topic to the page. 
Love and Light!

thread_title:  Alphabetical order for uses? 

message: In the info box, I have changed "9.24 (see text)" to "9.24, 12.4, 13.3", the format used in Sulfuric acid and Phosphoric acid. There are good reasons for the 'see text' note, but it's not clear what part of the text is meant. It could refer to Lewis acidity, or it could refer to the section discussing boric acid in solution with other species (as in natural waters).
The articles on the other polyprotic acids simply list the values; it should be clear to a reader with knowledge of the concept of the dissociation constant that this refers to pKa1, pKa2 and pKa3, and the solvent is water. pKa by definition refers to Brønsted acidity, so the Lewis acidity discussed in the article should not impact the values given here.
Some readers probably come to this article just for the pKa and other basic properties. Some possibilities for presenting the acidity:
- Keep this version (with 3 values)
- Revert to "see text", but with a link to the intended section
- Provide just the first dissociation constant
- Indicate the mixed Lewis/Brønsted acidity in the infobox (may be too technical for some readers)

message: However, other sources say that boric acid is also a tribasic Brønsted acid, with successive ionization steps and acidities as follows:
	
 Since the value of Ka1 is comparable to that of the reaction with OH−, the concentrations of BO(OH) and B(OH) are similar.
I have removed the above items from the main article for the following reason: The paper reporting these species is purely theoretical. The abstract reads "pH ranges of existence of boric acid and its ionic species H2BO3− , HBO32− , BO33− , and B(OH)4− in aqueous solutions are calculated using Mathcad software package." This is speculation, not supported by any physical evidence. Petergans (talk) 12:41, 20 July 2018 (UTC)
thread_title:  Unsupported material 

message: Note that Boric acid exists as a fine powder of slippery plates (ala graphite, wiki notes lubrication properties) so the "cut up the insect like glass" doesn't make sense. The lit says roaches acquire a static charge while moving and the powder (c.f. diatamaceous earth) sticks to their bodies being ingested on insect self-cleaning actions AND entry into and blockage of insects spiracles preventing respiration. Many animals and birds take "dust baths" to relieve themselves of arthropod parasites in the same manner.
