उत्तर
White silver chloride turns grey in sunlight when it is exposed to sunlight. This results from the light-induced breakdown of silver chloride into grey silver and chlorine.
\[\ce{2AgCl_{(s)} ->[Sunlight] 2Ag_{(s)} + Cl2_{(g)}}\]
This is a type of decomposition reaction.
Notes
Students should refer to the answer according to their questions.
