Give reason why:
$(i)$ White coloured silver chloride turns grey when kept in sunlight.
$(i)$ White coloured silver chloride turns grey when kept in sunlight.
(N/A) When white silver chloride $(AgCl)$ is exposed to sunlight,it undergoes a photochemical decomposition reaction.
In this process,silver chloride decomposes into metallic silver $(Ag)$ and chlorine gas $(Cl_2)$.
The chemical equation for this reaction is: $2AgCl(s) \xrightarrow{\text{sunlight}} 2Ag(s) + Cl_2(g)$.
The grey colour is due to the formation of metallic silver,which is grey in appearance.
