Question

In the reaction between ozone and hydrogen peroxide H2O2 acts as 1) oxidising agent 2) reducting agent
3)bleaching agent 4) both oxidising
and bleaching agent​

Answer 1

Ozone + Hydrogen Peroxide. An O3/ H2O2 system is an advanced oxidation process (AOP) in which hydrogen peroxide (H2O2) is used in conjunction with ozone (O3) to enhance the formation of hydroxyl radicals (·OH). The hydroxyl radical is a stronger oxidant that molecular ozone alone.

Answer 2

Ozone is a much stronger oxidising agent and so hydrogen peroxide is made to act as a reducing agent as evident from the given reaction.
