State the change in colour observed in following case mentioning the reason:
Silver chloride is exposed to sunlight.
What happens when silver chloride is exposed to sunlight? Write a chemical equation for this reaction. Also give one use of such a reaction.
उत्तर
Photolytic Decomposition is the process by which silver chloride breaks down into silver and chlorine when exposed to sunlight. Silver metal and yellowish chlorine gas are the byproducts of the breakdown of white silver chloride.
The chemical reaction is given as follows:
\[\ce{2AgCl(s) ->[Light][Decomposition]2AgCl(s) + Cl2(g)}\]
