Question

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

Answer 1

Answer:

As it is decomposes on coming in contact with sunlight.

2AgBr------------2Ag+Br2

Explanation:

Answer 2

Answer:

When exposed to light, reagents such as silver bromide (AgBr) degrade. As a result, they are maintained in dark bottles in the lab to avoid light exposure and disintegration.

Explanation:

Silver bromide is a photolytic material, meaning it degrades when exposed to sunshine by a photodecomposition reaction.

The dark-colored bottles block the passage of light, preventing light from reaching the silver bromide in the bottles and preventing its disintegration.

They function as a filter, preventing responses. As a result, dark-colored bottles are used to hold silver bromide.

When silver bromide (AgBr) is exposed to air on open surfaces, a chemical reaction occurs, resulting in the creation of silver metal and bromine gas. This reaction is known as a photolysis reaction.

                              $AgBr$   →   $Ag^+ +Br^-$
