8. Redox reactions

Answer

Following the steps as in part (A), we have the oxidation half reaction equation as:-

Fe2+(aq)→ Fe3+(aq) + e-

And the reduction half reaction as:-

H2O2(aq) + 2H+(aq) + 2e-→ 2H2O

Multiplying the oxidation half reaction by 2 and then adding it to the reduction half reaction, we have the net balanced redox reaction as:-

H2O2(aq) + 2Fe2+(aq) + 2H+(aq)→ 2 Fe3+(aq) + 2H2O
