Question
Answer the following question.
2 g of silver chloride is taken in a china dish and the china dish is placed in sunlight for some time. What will be your observation in this case? Write the chemical reaction involved in the form of a balanced chemical equation. Identify the type of chemical reaction.

Solution
When 2 g of silver chloride, AgCl, is kept in sunlight then AgCl breaks down into Ag and C12. The color of the silver chloride turns to grey.
The following change can be represented by the chemical reactions as:
\[\ce{2AgCl(s)->[sunlight] 2Ag(s) + Cl2(g)}\].
This type of reaction is an example of a photochemical decomposition reaction.
