a H 2 O 2 + O 3 → H 2 O + 2 O 2 b H 2 O 2 + A g 2 O → 2 A g + H 2 O + O 2 Role of hydrogen peroxide in the…

a H2O2+O3H2O+2O2
b H2O2+Ag2O2Ag+H2O+O2
Role of hydrogen peroxide in the above reactions is respectively:
  1. Oxidizing in a and reducing in b
  2. reducing in a and oxidizing in b
  3. reducing in a and b
  4. oxidizing in (a) and b

Solution

O3 is reduced into O-2 ion and
Ag2O is reduced to Ag so
H2O2 is reducing agent in both a and b
