Question

Give an example of a photochemical reaction involving silver salt and water

Answer 1

An example of photo chemical reaction is when silver bromide (4AgBr) , in presence of sunlight, breaks down into 2Ag2Br and Br2

Answer 2

Hey dear,

● Photochemical reaction -
- Reactions in in which light energy is absorbed to carry out the reaction is called photichemical reaction.


● Examples -
1) Photochemical reaction involving silver salt -
Silver chloride decomposes in presence of UV light to metallic silver & chlorine gas.
2AgCl2 + UV light --> 2Ag + Cl2

2) Photochemical reaction involving water -
During photosynthesis, carbon dioxide & water are converted to glucose & oxygen in presence of sunlight.
6CO2 + 6H2O + sunlight --> C6H12O6 + 6O2



Hope this helped you...
