Silver iodate (AgIO3) is a light-sensitive, white crystal composed of silver, iodine and oxygen. Unlike most metal iodates, it is practically insoluble in water.


Silver iodate can be obtained by reacting silver nitrate (AgNO3) with sodium iodate or potassium iodate. The by-product of the reaction is sodium nitrate.[1]

Alternatively, it can be created by the action of iodine in a solution of silver oxide.


Silver iodate is used to detect traces of chlorides in blood.

Silver nitrate reacts with iodate to form the precipitate of silver iodate, and the precipitate is transferred to silver nitrate.
