Talk:Periodic acid

Technical
First of all, the article says: "In dilute aqueous solution, periodic acid exists as discrete hydronium (H3O+) and metaperiodate (IO4−) ions." This seems very confusing to someone unfamiliar with the subject. For example, could aqueous possibly be wiki linked? Could it be explained more so it is easier for a wider audience to understand? Also, the symbol equation IO4− + 6 H2O IO65− + 4 H3O+ could maybe have the word equation under it to make it easier to understand.  Puffin  Let's talk! 22:20, 3 April 2012 (UTC)

Chembox
I've merged the two chemboxes for orthoperiodic and metaperioidc acids to give a single box for periodic acid in general. The second chembox was so far down the page that it could be very easily overlooked, also many of the values had been (wrongly) duplicated in both boxes. I'd advise anyone making future changes to the chembox to by especially careful about it - the normal practice of just pulling data off MSDS's wont do, there are two different compounds and their values are different. Also the Chembox code wasn't really designed to handle 2 different compounds in the same box, it's taken a fair amount of tinkering to get this to work, so be careful about that too.

I deleted the density, the value given of 1.4kg/m3 is obviously wrong, and even guessing 1.4 g/cm3 probably wrong, I think it close to 4.4 based on a calculation website. I couldn't find a reference online. Looking at the edit (24 March 2014), I don't see where the value comes from. — Preceding unsigned comment added by 24.96.23.124 (talk) 15:33, 19 September 2015 (UTC)

Wrong equasion?
The first equasion on the page:


 * H5IO6 + H+ + 2 e− → + 3 H2O     E° = 1.6 V

Doesn't seem to contain Periodic acid (HIO4) or iodic acid (HIO3), but the text refers to both. It does contain the formula for orthoperiodic acid (H5IO6) but the text makes no reference to that.

 * I've tried to clarify that. Any better? --Project Osprey (talk) 12:09, 28 June 2019 (UTC)

" Like all periodates it can exist in two forms..."
That's not what the page on potassium periodate says! Bruce Mardle (talk) 12:56, 31 October 2021 (UTC)
