प्रश्न
What is observed when silver chloride is exposed to sunlight? Give the type of reaction involved.
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.
