Iodate
Encyclopedia : I : IO : IOD : Iodate
An iodate is a salt of iodic acid. In the iodate anion, iodine is bonded to three oxygen atoms and the structural formula is IO3−.
Iodates are a class of chemical compounds containing this group. Examples are sodium iodate or NaIO3 and calcium iodate or Ca(IO3)2. Iodates resemble chlorates with chlorine instead of iodine.
In acid conditions, iodic acid is formed. Potassium hydrogen iodate (KH(IO3)2 is a double salt of potassium iodate and iodic acid and an acid as well. Iodates are used in the Iodine clock reaction.
