Soujanya's newly purchased silver was found to be darkened after 2-3 months due to tarnishing.
• Silver, over time, reacts with the various suplhur components present in atmosphere.
• This results in the formation of a layer of silver sulphide on the surface of silver.
2Ag + S → Ag₂S
• The compound, silver sulphide, is black in colour. Therefore, the silver material appears dark after 2-3 months.
• This process of darkening is called silver tarnishing, means decrease in the lustre of the metal.
