Electrode should be mentioned[edit]

Hi,

I am not really used to Wiki, but i want mention, that AgCl is also really important for reference electrodes. I thik it must be mentioned !!! And thus also the conductivety could be interesting.

electrodes[edit]

apparently a silver chloride gel is used for bioelectric electrodes. presumably because silver doesn't create a galvanic cell with skin electrolytes? - Omegatron 01:49, Apr 25, 2005 (UTC)


resource for analysts/chemists[edit]

I'd like to see some discussion of getting silver chloride into soluble, analyzable forms. When I was investigating and developing flame atomic absorption methods, the not-well-known knowledge that AgCl dissolves rather readily in concentrated HCl would have saved me a bunch of time. As it was I went to sites on jewelsmithery to learn this and confirmed it analytically. If wikipedia had had it, it would have been a lot nicer. Let's make this a true resource for chemists and analysts! Thanks, Nick Lockard 21:36, 16 May 2007 (UTC)

Uhoh, I also thought AgCl does not dissolve in concentrated HCl.
And as so, it could not be separated from Au3+ this way.
Although it likely slowly falls down from the solution if HCl can evaporate out.
Added quick info about solubility in HCl and NH4OH into the infobox.
The "NH4CO3" formulae in the infobox wasn't mine (added 2009-05-19), thus I don't know what it may mean - carbonate or bicarbonate; someone who knows should correct it.

Infobox[edit]

I'm moving the old infobox here as I am replacing it with a new chembox.

Ductility of AgCl[edit]

From the book "Understanding Batteries" by R.M. Dell, published by the Royal Society of Chemistry: "[Silver chloride] is an unusual inorganic material in that it can be cast and rolled like a metal..." page 87.

This sounds hard to believe; a salt being ductile. I could not find any other confirmation of silver chloride's ductility. Maybe someone with some silver chloride can confirm this interesting fact. I will continue to search for another explanation... Kevin Schostek (talk) 01:13, 3 June 2009 (UTC)Reply[reply]

Today I checked AgCl ductility and malleability on crystals. It works. Igor M Olekhnovitch (talk) 15:32, 27 August 2009 (UTC)Reply[reply]

Use in deodorant[edit]

Silver chloride is used in deodorants (e.g. Degree Silver Ion Technology). If anyone knows what for, please illuminate this on the article, I'm probably not the only one looking it up on Wikipedia to figure out why. Vikingurinn (talk) 14:00, 12 May 2011 (UTC)Reply[reply]


Deodorants use AgCl or other slightly soluble Ag salts to take advantage of the antimicrobial properties of Ag+. Microbial metabolism is largely responsible for body odor. 192.206.119.3 (talk) 22:54, 26 November 2012 (UTC)Superfluid.192.206.119.3 (talk) 22:54, 26 November 2012 (UTC)Reply[reply]

Who discovered or first documented silver chloride?[edit]

This article on Photography, section "Precursor technologies" states that Georg Fabricius discovered silver chloride. The article on Fabricius contains no indication that he experimented with chemistry.

The reference given is: <ref< Georges Potonniée (1973). The history of the discovery of photography. Arno Press. p. 50. ISBN 0-405-04929-3</ref<

It would improve this article, the "Photography" article as well as the "Fabricius" article if the first discoverer and/or documentator was cited.--TGC55 (talk) 11:38, 17 May 2013 (UTC)Reply[reply]
