What type of chemical reaction takes place when silver bromide is exposed to sunlight?
Light decomposition reaction.
Silver bromide is a light-sensitive compound that is it gets decomposed when exposed to light.
So when silver bromide is exposed to sunlight, it gets decomposed to give silver metal and bromine gas is liberated. The reaction is called a photolysis reaction. The word photolysis can be broken into two parts photo means light and lysis means breaking. So photolysis means breaking of a compound in the presence of light.
Silver bromide is widely used in photography.
The reaction is given as follows:
2AgBr→ 2Ag + Br2
