Space-filling model of the iodate anion, IO₃⁻

An iodate is a salt of iodic acid. In the iodate anion, iodine is bonded to three oxygen atoms and the molecular formula is IO₃⁻. The molecular geometry of iodate is trigonal pyramid.

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.
