Question:
An acidic solution of hydrogen peroxide behaves as an oxidising as well as the reducing agent. Illustrate it with the help of a chemical equation.
Solution:
H2O2 + 2HI → I2 + 2H2O
Here H2O2 cat as an oxidizing agent
HOCl + H2O2 → H3O+ + Cl– + O2
Here H2O2 act as reducing agent
o, we can see that H2O2 acts as an oxidising agent in the first reaction as it increases the oxidation number of I- in HI from -1 to 0 in I2.
Similarly, H2O2 acts as a reducing agent in the second reaction as it decreases the oxidation number of Cl+ in HOCl from +1 to -1 in Cl-.
