Question

What change is observed if white silver chloride is placed in sunlight? Write an equation of the reaction and explain the type of reaction.

Answer 1

"The change that occurs when white silver chloride is placed in sunlight is discussed below:

By exposing the white silver chloride in the sunlight, a sudden change occurs which produces the black metallic colored silver with the evaporation of Chlorine gas.

2AgCl → 2Ag + Cl2

This process is called as photodecomposition reaction.

"

Answer 2

This produces the black metallic coloured Silver and chlorine gas.

2AgCl=> 2Ag +Cl2
This is called as photo decomposition reaction.
