The reason for colour changing of the silver anklet after few days is due to the formation of silver sulphide.

CORROSION -

  • The blackening of silver in the air is due to the phenomenon known as corrosion.
  • The process is also known as the tarnishing of silver.
  • The silver reacts with the hydrogen sulphide present in the atmosphere to form silver sulphide.
  • The silver sulphide is a black-colored layer formed on the white lustrous layer of the silver.
  • The reaction can be given as -

Ag + H_2SAg_2S + H_2
