Question

Give scientific reasons:

When silverware is exposed to air, it turns blackish after sometime

Answer 1

The reason for this is that the silver metal reacts with sulphur present in the atmosphere and forms silver sulphide. As a result, a layer of silver sulphide or Ag2S is formed on the surface of the silver articles. So the articles appear to be dull and black. It is referred to as corrosion or tarnishing of silver.
