Why Silver Bromide Stored in Dark Bottles?

Silver chloride

Silver chloride
Silver chloride is a chemical compound with the chemical formula AgCl. This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl+ and Pb2+).

decomposes into silver and chlorine gas when exposed to sunlight. Dark-coloured bottles interrupt the path of light such that light cannot reach silver chloride in the bottles and its decomposition is prevented.

Why is silver bromide stored in dark bottles in the laboratories write the chemical equation to justify your answer?

Answer: Silver Bromide is a photolytic substance i.e it breaks down in the presence of sunlight through photo decomposition reaction. That's why it is stored in dark colored bottles in labs.

Why silver bromide should be kept away from sunlight?

Silver Bromide (AgBr) when kept in open surfaces will get exposed to air and a chemical reaction will occur leading to the formation of Silver and Bromide gas. AgBr --> Ag+ + Br-. Hence, it is always stored in brown bottles away from sunlight.
