    Removing Tarnish from Silver Compound Interest

    Silver tarnishes in air to form a black coating of silver sulphide, which has the formula Ag 2 S. The chemical equation for the formation of silver tarnish following reaction with hydrogen sulphide (H 2 S) is as follows:. 2 Ag (s) + H 2 S (g) → Ag 2 S (s) + H 2(g). There’s speculation that, in the present day, tarnishing of silver actually occurs more quickly due to the increased amounts
