Question

explain the decomposition of silver chloride into silver in the presence of sunlight experimentally​

Answer 1

A photodecomposition reaction is a type of decomposition reaction in which the reactant absorbs energy from photons and breaks down into its constituents. The decomposition into dioxygen and an oxygen radical, as illustrated by the chemical equation given below, is an example of a photo decomposition reaction.

Silver halides especially Silver chloride undergo decomposition in presence of sunlight to produce silver metal and a halogen gas (chlorine or bromine gas).

The reactions are as follows:

2AgCl (sunlight)→2Ag+Cl2
