\nSilver artefacts get tarnished in air due to the formation of silver sulphide.
\n<\/section>\n
\nSilver tarnishes when it reacts with sulfur compounds present in the air, such as hydrogen sulfide (H2S). This reaction forms a black layer of silver sulfide (Ag2S) on the surface of the silver.
\n<\/section>\n
\nThe reaction is 2Ag(s) + H2S(g) -> Ag2S(s) + H2(g). Tarnishing is accelerated in polluted air or environments with higher concentrations of sulfur gases.
