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[edit]

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.

Uses[edit]

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