Where can I find this chemistry answer?

Question

I have to find the four oxyanions and oxyacids of iodine.

The only information i've been given is that "like chlorine, iodine is a halogen and forms similar compounds."

Please help, I just need a website to read up on or something.

I live out over an hour (by car) from a library, and have no means of transportation. i've looked all over the internet, but still can't find it. this is a summer paper; i can't even ask my teacher about it. any help will be extremely valuable! :0 thanks.

Answer 1

I assume that you don't have access to a textbook on inorganic chemistry, which would tell you this.

If you know the answer for chlorine, the answer for iodine is very similar, although there are some interesting differences in the highest oxidation state.

Look up hypoiodous acid, iodous acid, iodic acid and periodic acid in Wikipedia or on Google.

And don't believe anyone who tells you that the first of these is HIO. It should always be written HOI. All these oxyacids contain an acidic H-O- group.

Answer 2

Wikipedia is actually very good here.

Oxyanions are ions of the element combined with oxygen. The chlorine oxyanions are similar to the iodine ones. Hypochlorite is the simplest. Work from there.

Answer 3

HIO = Hypoiodous acid;  IO- = Hypoiodite

HIO2 = Iodous acid;  IO2- = Iodite

HIO3 = Iodic acid;  IO3- = Iodate

HIO4 = Periodic acid;  IO4- = Periodate

Answer 4

Try "www.webelements.com"

Pick Iodine and they'll give you common compounds,

Oxyacids, and lots more.
