Silver: The mineral native Silver information and pictures

Hydrogen sulfide (H 2 S) is found in the atmosphere in small quantities, and when silver is exposed to normal air it reacts to the hydrogen sulfide, causing the tarnish. Egg yolks, which contain sulfur compounds, should be kept away from silver. Several chemical coats are available to protect it from tarnish, and certain polishes remove tarnish.

Silver to Black - and Back | Journal of Chemical Education

Silver and silver-plated objects react with sulfur and sulfur compounds to produce silver sulfide (Ag2S), or tarnish. Contact with materials that contain sulfur compounds, such as hardboiled eggs, mayonnaise, mustard, and rubber bands can cause tarnish. In air, a silver object can tarnish owing to the reaction of silver with hydrogen sulfide (H2S). This is a gas found in the air as a result of ...
