Properties of metaperiodic acid?
I found a (potential) offer for metaperiodic acid and I thought it sounded really interesting. So I looked it up and looked through many sites, but I
couldn't find any source for its properties.
Does anyone here know anything about it?

Your question is very general, and hence we cannot give specific answers.
Periodic acid is a strong oxidizer. Salts of periodic acid, such as KIO4, NaIO4, and Na3H2IO6 also are strong oxidizers and they also form many
interesting complexes with transition metals in unusually high oxidation states.
It can be used in organic chemistry to split diols with the two OH-groups on adjacent carbon atoms, with the HO-group and broken carbon bond connected
to an O=group.
Periodates.
If I look at your signature to the list of collected compounds, and if I look at your posts, then, however, I think it is better to first try to get
some other more common and basic chemicals. Periodates and periodic acid are expensive and are not the first thing for an amateur lab. If you want to
do interesting experiments with these compounds, then you also need other reagents to do the experiments with.
I have written a web page about starting a home lab, it may be interesting for you. It also contains info on which chemicals to obtain as a starter.

I think your google is broken when I googled it and got lots of info, its got a wiki page https://en.wikipedia.org/wiki/Periodic_acid
Its probably described in one of the inorganic books in our library too
I am wg48 but not on my usual pc hence the temp handle.
Thank goodness for Fleming and the fungi.

I don't know who invented mRNA vaccines but they should get a fancy medal and I hope they made a shed load of money from it.

Ah. Okay. I asked so unspecifically since I really had no idea what the compound was. Or I thought I didn't, at least.
Guessing from your answer, metaperiodic acid is the same as the normal periodic acid? Because I did find answers to what periodic acid was, but I
assumed periodic acid and metaperiodic acid had different properties.
I'll take a look at the site and steer away from this compound for now.
Thank you!

I had no idea that periodic and metaperiodic acid were the same thing. Sorry.

I did know what it was too which is why I googled it.
Most chemicals have various names which can make it difficult to find info on them. Some times when you google something the results do not look
relevant because the displayed results don't mention the search term but frequently it is mentioned if you go to the site. Wiki and many sites give
synonyms for compounds.which is why they appear in the search results.

The common form of periodic acid is the so-called ortho form: H5IO6. A better description of this acid is IO(OH)5. With some difficulty, this
orthoperiodic acid can be converted to metaperiodic acid:
H5IO6 ---> HIO4 + 2 H2O
Salts also exist in multiple forms. I have some NaIO4 (sodium metaperiodate), and I once made Na3H2IO6 (sodium hydrogen orthoperiodate, which has
three hydrogens replaced by sodium) from NaI, NaOH and Cl2.
There are many anionic species, which have orthoforms and metaforms. The metaforms can be thought of as being derived from orthoforms by splitting off
water or basic oxides.
Two other examples are:
- ortho/meta phosphoric acid: H3PO4 and HPO3 (the latter in fact is a polymeric species, and better can be written as (HPO3)n with large n).
- ortho/meta vanadate ion: VO4(3-) ion and VO3(-) ion. The latter again is a polymeric species.
There are more (e.g. from tellurium, second row transition metals in high oxidation states)
Ortho/meta forms also exist in covalent compounds (e.g. certain organics, esters which can be present in ortho form (e.g. tetramethyl orthocarbonate
vs. dimethyl metacarbonate). Orthocarbonic acid is C(OH)4, while metacarbonic acid (the standard stuff) is CO(OH)2, usually written as H2CO3).
I hope this explains a little bit the meaning of ortho and meta.
