2g of silver chloride is taken in a china dish and the china dish is placed in sunlight for sometime. What will be your observation in this case?

When 2g AgCl is kept in sunlight then AgCl breaks down into Ag and Cl₂. The colour of silver chloride turns to grey. The following change can be represented by the chemical reactions, 2AgCl(s) →sunlight 2Ag(s) + Cl₂(g) This type of reaction is an example of photochemical decomposition reaction.
