Feb 4, 2017

$\text{Iodic acid.........}$

#### Explanation:

$\text{Iodic acid}$ has formula $H I {O}_{3}$, and iodine here has a formal $+ V$ oxidation state. Its salts are known as $\text{iodates.}$

Iodic acid, or hydrogen iodate.

#### Explanation:

The halogens have a lot of different oxidation states. Chlorine is the worst. The most common is called -ate, the one with one O less is called -ite (same goes for sulfate-sulfite nitrate-nitrite).

Since the halogens also form halides, the series goes (I take chlorine as an example):

$C {l}^{-}$ =chloride
$C l {O}^{-}$ =hypochlorite (hypo means under)
$C l {O}_{2}^{-}$ =chlorite
$C l {O}_{3}^{-}$ =chlorate
$C l {O}_{4}^{-}$ = (su)perchlorate (super means above)

Most of these also have an iodine version.
All of these are oxidators, they themselves being reduced to elemental form or even to the -ide form.
