Question

Balance the following redox reactions by ion – electron method: H 2 O 2 (aq) + Fe 2+ (aq) → Fe 3+ (aq) + H 2 O (l) (in acidic solution)

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:-

H₂O_2(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:-

H₂O_2(aq) + 2Fe²⁺_(aq) + 2H⁺_(aq)→ 2 Fe³⁺_(aq) + 2H₂O

Balance the following redox reactions by ion – electron method:H2O2 (aq) + Fe2+ (aq) → Fe3+ (aq) + H2O (l) (in acidic solution)
