Question

Silver metal does not combine easily with oxygen but silver jewellery tarnishes after some time. How?

Answer 1

Answer:

This is because when silver is exposed to air, it reacts with sulphur compounds in the air. It is this reaction with sulphur compounds in the air that cause the silver to tarnish and not the reaction with oxygen. The silver forms a tarnish, which is a compound of the silver and sulphur-Ag2S.
