Metal displacement reaction. Start of an experiment demonstrating the reaction of a copper strip with silver nitrate solution in a test tube held by a test tube holder. Copper is a more reactive metal than silver. Over time, copper displaces (replaces) the silver in the solution to form a solution of copper nitrate. The silver that is starting to be displaced out of solution crystallizes as a grey coating on the copper.
