In which of the following reaction H2O2 acts as a reducing agent?(P) H2O2+2H++2e−→2H2O(Q) H2O2−2e−→O2+2H+(R) H2O2+2e−→2OH−(S) H2O2+2OH−−2e−→O2+2H2O

P) H2O2 (aq) acting as an oxidizing agent in an acidic solution. Write the balanced equation.H2O2+2H++ 2e−→2H2O Q) H2O2 (aq) acting as a reducing agent in an acidic solution. Write the balanced equation.H2O2aq→O2+2H++ 2e− R) H2O2 (aq) acting as an oxidizing agent in basic solution. Write the balanced equation H2O2+ 2e−→2OH− S) H2O2 (aq) acting as an reducing agent in basic solution. Write the balanced equation H2O2+2OH−−2e⊖→O2+2H2O∴ Correct answer is (2)
