Talk:Acetate

Help? I need a describtion for the material acetate for my graphics coursework. All I am able to say at the moment is that it's transparent. Does anyone know whether it a plastic?

This could be one of several materials, but is most likely cellulose acetate. Yes, it is a plastic. Physchim62 08:52, 15 October 2005 (UTC)

Abbreviation

IMHO, this article is erronous when it ascribes the abbreviation Ac to acetate. Ac is in fact the abbreviation for acetyl; acetate therefore is AcO. Source: IUPAC recommendations. Physchim62 08:52, 15 October 2005 (UTC)

• No, I don't agree: Ac is a good and common abbreviation for acetate, notably in comparison to other acids (mostly inorganic) such as HAc and HCl and salts such as NaAc and NaCl. The above IUPAC reference merely states that the Ac abbreviation is used for Acetyl, which is also correct. That doesn't mean at all that Ac for acetate is incorrect: many other usages of the Ac denomination can be found on the AC disambiguation page. Wim van Dorst 10:05, 17 October 2005 (UTC).
  • I use Et for ethyl, and for ethanoate (i.e. acetate) EtOO-. However, I believe that the "traditional" term Ac would be used for either the acetyl or the acetate ion. Justification: HAc would not be mistaken for, say, acetyl hydride 218.103.137.150
    • EtOO- would be the anion formed by deprotonation of ethyl hydroperoxide. Physchim62 (talk) 09:39, 10 January 2006 (UTC)

Please add relevant sources supporting the "good" and "common" usage of Ac symbol for acetate, if applicable. I've added IUPAC inorg. (already mentioned above), and org. chem. refs for acetyl. ​​ —Mykhal (talk) 06:09, 22 August 2019 (UTC)

Is this the correct formula?

I was under the impression that acetate was C2H302(-1). What's up?

• It is. The article doesn't dispute it, does it? Wim van Dorst 09:48, 19 October 2005 (UTC).
• Yes, C2H3O2 is the same thing as CH3CO2, just expanded to reflect the chemical structure. gxti 22:23, 28 October 2005 (UTC)

Vandalism alert

The page keeps being vandalized, someone keeps adding the line "Poopy in your face", and for some reason the chart and table describing the molecular structure of acetate has disappeared. Ovni (talk) 21:16, 28 January 2008 (UTC)

Not to be confused with actinium?

Is that bit really nescassary? The two words are quite different. They only share the same first two letters, so that would be like confusing "click" with "claustrophobic" Alecjw (talk) 09:15, 9 June 2009 (UTC)

• The abbreviation for acetate (Ac) may be confused with the elemental symbol for Actinium (Ac). However, actinium acetates (!!) notwithstanding, there's probably little chance of ambiguity in a paper arising from this shared abbreviation. Eutactic (talk) 06:00, 6 August 2009 (UTC)

Ah yeah, good point, I hadn't thought of that. Searching "Ac" gets you to a disambiguation page anyway, so yeah. It's a bit like that annoying new element, Cp. Cp means cyclopentadienyl, but noone cares about copernicium, so it should be alright Alecjw (talk) 10:13, 6 August 2009 (UTC)

Pronunciation

It's listed as pronounced /ˈæsɪteɪt/ but I've always said/heard pronounced /ˈæsɛteɪt/. Am I alone on this? Attys (talk) 02:16, 19 September 2011 (UTC)

energy content??

Acetate fermentation releases 36KJ per molecule ???? All the pertaining Wikipedia pages quote the same statistic. 66.235.38.214 (talk) 18:01, 4 October 2012 (UTC)

Looks about right. What's the problem? --Rifleman 82 (talk) 18:23, 4 October 2012 (UTC)

36 kJ / molecule is 16 orders or magnitude larger than nuclear fusion! The Gibbs free energy of the reaction is normally expressed as kJ/mol, and as it is confusing, I will change it to those units. Tomásdearg92 (talk) 13:13, 11 November 2012 (UTC)

"Acetate" discs

The esters section lists "acetate discs" as an example. Acetate discs are coated with nitrocellulose, not acetate. The acetate disc article confirms this but I put this in talk as I'm not a chemist and somebody with more expertise should verify this and correct.

A better example of use would be eyeglass frames. — Preceding unsigned comment added by Babaluma (talk • contribs) 18:03, 11 May 2013 (UTC)
