Is hydrobromic acid an oxoacid? The hydrobromic acid page says that it is. Jiminyjimjim (talk) 20:44, 9 March 2008 (UTC)[reply]

No, hydrobromic acid is not an oxoacid since it does not contain oxygen.

The article currently says: "Although carboxylic acids fulfill the criteria above, they are not generally considered as oxoacids." Weasel words. The IUPAC Gold Book definition of oxoacids gives "RC(=O)OH" as an example of an oxoacid. J G Campbell (talk) 06:43, 28 October 2008 (UTC)[reply]

In the first line of the article Keto acid it states that they are also known as Oxo acids or Oxoacids.

Well, nope. The keto acid article refers to a special kind of carboxylic acids (which are also oxoacids) that are sometimes shortened to "oxo acids". Thomas J. S. Greenfield (talk) 12:31, 25 March 2014 (UTC)[reply]

Inorganic oxoacids typically have a chemical formula of type H_mXO_n, where X is an atom functioning as a central atom...

Can't X also be attached to other atoms? Equivalently, but differently put, can't X stand for a whole group?

If X is allowed to be a whole group, then this paragraph can be condensed somewhat. 89.217.9.188 (talk) 03:32, 17 January 2015 (UTC)[reply]

In a very simplified manner, the structure of an oxoacid molecule can be described as M-O-H, where, however, even other atoms or atom groups can be connected to the central atom M.

Why is this "very simplified"? It seems to be spot-on accurate, but confusingly stated. Because if we say the structure of the molecule "is" M-O-H, but then immediately qualify it by saying that this is not the actual molecule but only part of the molecule, that's confusing.

I changed this to: An oxoacid molecule contains the structure M-O-H, where other atoms or atom groups can be connected to the central atom M.

I also moved the two paragraphs commencing with this statement to the head of the section. By the way, I found the explanation of acid versus base tendency in these two paragraphs to be extremely useful. I wish I had encountered it before.

Do these two paragraphs apply to all oxoacids or only organic oxoacids?

Old version: oxygenium, derived from greek and meaning acid-maker

Oxy just means sharp or sour. It seems doubtful that Greeks had the concept of acid as such. I changed this.89.217.9.188 (talk) 01:18, 17 January 2015 (UTC)[reply]

For example, carbon dioxide, CO₂, is the anhydride of carbonic acid, H₂CO₃, and sulfur trioxide, SO₃, is the anhydride of sulfuric acid, H₂SO₄.

There is no page for "anhydride" per se in Wikipedia, but it points us to organic acid anhydride. There, it states "an acid anhydride is a compound that has two acyl groups bonded to the same oxygen atom". That implies at least a -(O=C-O-C=O)- structure inside there. There seem to be two definitions of the anhydride of an acid (or of an acid anhydride) floating around here. 89.217.9.188 (talk) 01:32, 17 January 2015 (UTC)[reply]

Many organic acids, like carboxylic acids and phenols, are oxoacids.

Are there any that are not??? 89.217.9.188 (talk) 01:36, 17 January 2015 (UTC)[reply]

Not sure. They have to be bound to the -H right? I can't think of an example that is not also bound to a -H. CH3COOH is bound to -H and probably many other organic acids are too; or all of them. 2A02:8388:1600:C80:BE5F:F4FF:FECD:7CB2 (talk) 20:16, 1 July 2016 (UTC)[reply]

Is H2SO4 an oxoacid? In the table below, it is not noted as one, so I am unsure. From the definition, it should be one right? But it is not in the table below. Also, could someone perhaps make the table a bit prettier? Highlight in slight different colours or so and make the header a bit larger? But this is style consideration, content is admittedly more important than style. 2A02:8388:1600:C80:BE5F:F4FF:FECD:7CB2 (talk) 20:16, 1 July 2016 (UTC)[reply]
