When silver metal is exposed to sulfur it reacts to form silver sulfide. Silver sulfide is commonly known as tarnish and turns the surface of silver objects dark and streaky black (see Figure below ). The sulfur that contributes to tarnish can come from traces of sulfur in the air or from such as eggs. The word equation for the process is: The silver and the sulfur are the reactants in the equation, while the silver sulfide is the product. Another common che
