Question

Why the colour of silver chloride changes when exposed to sunlight?​

Answer 1

Explanation:

• When white Silver chloride exposed to sunlight it produces to black metallic colured Silver along with liberation of Chlorine gas. This is a photodecomposition reaction.

• Silver chloride turns grey on exposure to sunlight because it decomposes in presence of sunlight to give silver (Ag). 2. Oxidation of copper powder gives black colour copper oxide

Answer 2

when silver chloride is exposed to sunlight it undergoes photochemical decomposition forming black metallic colour silver and greenish yellow gas chlorine. Thus, the change in colour is observed due to the oxidation of silver chloride in the presence of Sunlight.
