Iodous acid is the chemical compound with the formula HIO 2. Its salts are named iodites ; these are exceedingly unstable and have been observed but never isolated. [ 1 ] They will rapidly disproportionate to molecular iodine and iodates .
The salt I 2 Sb 2 F 11 is dark blue, and the blue tantalum analogue I 2 Ta 2 F 11 is also known. Whereas the I–I bond length in I 2 is 267 pm, that in I + 2 is only 256 pm as the missing electron in the latter has been removed from an antibonding orbital, making the bond stronger and hence shorter.
Hypoiodous acid is an inorganic compound with the chemical formula H I O. It forms when an aqueous solution of iodine is treated with mercuric or silver salts. It rapidly decomposes by disproportionation: [2] 5 HIO → HIO 3 + 2 I 2 + 2 H 2 O. Hypoiodous acid is a weak acid with a pK a of about 11. The conjugate base is hypoiodite (IO −).
Iodites (including iodous acid) are highly unstable and have been observed [1] but never isolated. [citation needed] They will rapidly disproportionate to molecular iodine and iodates. [2] However, they have been detected as intermediates in the conversion between iodide and iodate. [3] [4]
2 s 2 o 2− 3 + i 2 → s 4 o 2− 6 + 2 i − After some time the solution changes color to a very dark blue, almost black. When the solutions are mixed, the second reaction causes the iodine to be consumed much faster than it is generated , and only a small amount of iodine is present in the dynamic equilibrium .
Calcium iodate, Ca(IO 3) 2, is the principal ore of iodine. It is also used as a nutritional supplement for cattle. It is also used as a nutritional supplement for cattle. Potassium iodate , KIO 3 , like potassium iodide , has been issued as a prophylaxis against radioiodine absorption in some countries.

Iodine pentoxide (I 2 O 5). Iodine oxides are chemical compounds of oxygen and iodine.Iodine has only two stable oxides which are isolatable in bulk, iodine tetroxide and iodine pentoxide, but a number of other oxides are formed in trace quantities or have been hypothesized to exist.
