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.[2]

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.[3]
