Talk:Silver chloride

Electrode should be mentioned

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

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

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

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

Ductility of AgCl

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)

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

Use in deodorant

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)

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)

Who discovered or first documented silver chloride?

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)

Hi, I'm going to be taking on this review. Reconrabbit 15:48, 23 February 2024 (UTC)

Comments

• Comments on the talk page regarding the discovery by Georg Fabricus have not been addressed. A better source on this or explanation would be great.
  • Better source added.
• Dates on photographic films (1727, 1816) aren't confirmed by the sources. Maybe it is from the dead link but a better source will be needed now. I will add citation needed tags to spots that I can't confirm with [4].
  • 1727 confirmed in source 7, 1816 confirmed in source 8.
• Ullman's Encyclopedia is cited many times on this page. It would benefit the article a lot if locations in the chapter or page numbers were provided, with sfn or rp templates or otherwise.
  • The reason I'm avoiding this is because I had trouble the last time I tried to do this. Would be nice if you could give me a few pointers. Keres🌕Luna ^edits! 15:36, 25 February 2024 (UTC)

  The way I would do it is like this: "Silver chloride has been known since ancient times. Ancient Egyptians produced it as a method of refining silver, which was done by roasting silver ores with salt to produce silver chloride, which was subsequently decomposed to silver and chlorine."

  Some people prefer sfn though . I haven't been able to find a few of the references in the text that should be referred to when trying to make an example though - do you have access to the text? I couldn't find the equations for silver nitrate to silver chloride specifically. Reconrabbit 16:24, 25 February 2024 (UTC)

  Yes, I do have access to the text. However, the equations are implied for a meththesis reaction, and do not need to be referenced. Keres🌕Luna ^edits! 17:09, 25 February 2024 (UTC)

  Added all the page numbers. Keres🌕Luna ^edits! 17:27, 25 February 2024 (UTC)

  Okay, looks good. Reconrabbit 17:40, 25 February 2024 (UTC)

• [12] "More info on Chlorine test" needs a full citation.
• Considering how much of the article is related to it, an image depicting silver chloride as used in photography would be useful, but not required.
• If cyanidation is the most common process used, it should be expanded on. Also, "cyanidation is the most commonly used" makes the sentence hard to follow.
  • Rephrased.

Chemistry

• "unreactive toward water" is it unreactive or insoluble?
  • Changed to insoluble.
• Indicating the photosensitivity of other silver halides belongs in its own paragraph.
  • Done. Keres🌕Luna ^edits! 19:21, 23 February 2024 (UTC)

Uses

• I did a quick literature search and the first thing I found was a lot of articles related to antimicrobial applications and nanoparticles of AgCl. It may be prudent to provide more than just a single sentence bullet point on this though it could just be a research trend related to medical uses of silver.
  • Added a new section.

Progress is going very well. Only thing that needs to be done is to give locations in "Silver, Silver Compounds, and Silver Alloys". Reconrabbit 05:45, 25 February 2024 (UTC)
