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.

Production

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.

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

Uses

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