Answer 2

Decomposition reaction in light.

Some liquid medicines are stored in dark-colored bottles because they can react to light, and keeping them in dark-colored bottles helps to keep the drugs from coming into touch with the light.

When chloroform reacts with light, it produces phosgene, which is a toxic gas. As a result, it's kept in an amber-colored container.

Dark-colored bottles block the passage of light, preventing light from reaching the silver chloride in the bottles and preventing its disintegration. Silver chloride is known to breakdown into silver and chlorine when exposed to light.
