Chemical Properties:
Yellow Solid
Uses:
In the laboratory, Auric chloride is a useful reagent for the determination of gold and other metals. It is a strong oxidizing agent and reacts with most metals, forming insoluble salts which can be filtered and assayed for their gold content. It is also used in the preparation of colloidal gold, which is widely used in the electronics industry.
Auric chloride is also used in electroplating, where it is used to deposit a thin layer of gold onto a metal surface. In the electroplating process, a solution of Auric chloride is mixed with a metal salt, such as copper sulfate. When electricity is applied to the solution, the gold ions in the Auric chloride react with the metal salt and deposit a thin layer of gold onto the surface of the metal.
