Why do we store silver chloride in dark-colored bottles?

Hint: You should know that there are photons present in the light. These photons have a role in the decomposition of some compounds. Now just use these hints to answer this question correctly.

Complete step by step answer:
Compounds Like Silver chloride are light-sensitive and they may react to light very fast to easily undergo photolytic decomposition reaction and lose their properties.

Here AgCl is converted to molecular Ag atoms by the effect of photons of light.
Dark-colored bottles interrupt the path of light such that light cannot reach silver chloride in the bottles and its decomposition is prevented. It is known that silver chloride decomposes to silver and chlorine in the presence of light. This silver formed is microscopic and turns blackish-grey in color. Hence, we lose the use of silver chloride. That's why they are to be stored in dark bottles to prevent the entry of light.
This is shown in the reaction given below:
$2AgCl(s)\quad \rightarrow \quad 2Ag(s)\quad +\quad Cl_{ 2 }(g)$
Other salts of silver are also examples, such as silver nitrate and Hydrogen peroxide also has a similar action.

Therefore, we explained why we store silver chloride in dark-colored bottles.

Note: We should also know that AgCl is converted to molecular Ag atoms by the effect of photons of light. This is the basis of black and white photochemistry in which AgCl the salt is exposed to light and the chemical process which is completed by the developer, a basic solution, the action of which stopped by the stop bath, a weak acid, and made fade-proof by the Fixer which removes all undeveloped silver salts from the emulsion.
