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.  `H_(2)O_(2)to2H^(o+)+O_(2)+2e^(ɵ)`   In which of the following reactions, `H_2O_2` act as a reducing agent?
