Hydrogen peroxide is a powerful oxidising agent, both in the acidic and alkaline medium. In acidic medium: H_(2)O_(2)+2H^(o+)+2e^(ɵ)to2H_(2)O In alkaline medium: H_(2)O_(2)+2e^(ɵ)to2overset(Theta)(O)H Hydrogen peroxide acts as a reducing agent towards powerful oxidising agents. In acidic medium: H_(2)O_(2)to2H^(o+)+O_(2)+2e^(ɵ) In alkaline medium, however, its reducing nature is more effective.
