Q. Silver gets corroded due to _____ in air:
Answer: Hydrogen Sulphide
Notes: Silver is a fairly stable metal and under normal circumstances does not corrode quickly. However, it is particularly susceptible to the effects of the sulfide radical. When exposed to air, silver reacts with Hydrogen sulphide in the atmosphere, especially in marine environment, and readily forms a blackish surface tarnish of silver sulphide.
