Why does silver tarnish?

Tarnish is a dulling which naturally occurs when silver reacts with sulfur or hydrogen sulfide in the air. Most people think silver tarnishes due to oxidation. But, chemically speaking, silver is not very reactive—it does not react with oxygen or water at normal temperatures. However, other metals in the alloy, usually copper, may react with oxygen in the air.
