What happens when silver bromide is exposed to sunlight

 Today we will discover what happens when silver bromide is exposed to sunlight and the chemical reaction that takes place.

 Silver bromide formula- AgBr

Silver bromide is a photosensitive substance like silver chloride. The colour of silver bromide is pale yellow or off-white and insoluble in water.

Silver bromide on exposure to sunlight decomposes into silver and bromine.

AgBr         Ag + Br

Silver bromide on exposure to sunlight turns grey. The reaction involves photolysis.

Photolysis:- When a substance undergoes decomposition on absorbing light energy. The reaction is called photolysis.

Silver bromide decomposition is used in black-and-white photography.
