Copper, being an unreactive metal do not react with acids under normal conditions. Curriculum Notes . When formed during acid-metal reactions, these compounds are usually referred to as salts. Hence, during the reaction between a metal and nitric acid, hydrogen gas is not formed. Silver react with nitric acid to produce silver(I) nitrate, nitrogen dioxide and water. But in the case of nitric acid (HNO3), copper does react with nitric acid as it is a strong oxidizing agent and the reaction is not as simple as of metal + acid. Apart from that, any oxide of nitrogen (NO 2, NO, N 2 O) is formed during the reaction. When this experiment is repeated with nitric or sulfuric acid instead of \(HCl\), it yields the same results: the clear limewater turns milky, indicating the production of carbon dioxide.
