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 .
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 −).
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.
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]
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.

The label will advise the appropriate dilution ratio, commonly 1:1000 or 1:100. Equipment to be sanitized should be thoroughly clean and left in contact with the solution for at least 2 minutes. Diluted iodophor is used extensively in the dairy industry for disinfecting milking parlors , particularly in the United Kingdom .
