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)

[edit] 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)

[edit] 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)
