Question

Chemistry Question on Bohr’s Model for Hydrogen Atom

What are the products of auto-photolysis of water?

A

H2{H_2} and O2{O_2}

B

Steam

C

H3O+{H_3 O^{+}} and OH−{OH^{-}}

D

Hydrogen peroxide

Answer

H2{H_2} and O2{O_2}

Explanation

Solution

Auto photolysis of water involves breakage of chemical bonds as the result of transfer of light energy to these bonds of water. It involves release of oxygen as a byproduct and also releases hydrogen

2H2O→4H++4e−+O22 H _{2} O \to 4 H ^{+}+4 e^{-}+ O _{2}
