Silver Nitrate Structure, Properties, and Uses of AgNO3

The reaction between silver nitrate and ethanol is explosive. The silver present in this compound is displaced by copper, which forms copper nitrate. The chemical equation for this reaction is given by 2AgNO 3 + Cu → Cu(NO 3) 2 + 2Ag; When heated to 440 o C, this compound completely decomposes to give oxygen, nitrogen dioxide, and silver.
