Talk:Oxyacid

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


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

Carboxylic acids are oxoacids
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)

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

(15/02/14)

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)

Inorganic oxoacids too narrowly characterized?
Inorganic oxoacids typically have a chemical formula of type HmXOn, 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)

Fixed this statement and moved 2 paragraphs
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?

Anachroetymology?
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)

Anhydride
''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)

Organic acids that are not oxoacids?
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)
 * 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)

H2SO4
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)
