1. Balance the following redox equations by the ion-electron method: (25 points) a. H2O2 + Fe+2 → Fe+3 + H2O (in acidic solution) b. Cu + HNO3 → Cu+2 + NO + H2O (in acidic solution) c. CN– + MnO4– → CNO– + MnO2 (in basic solution) d. Br2 → BrO3– + Br– (in basic solution) e. S2O3–2 + I2 → I– + S4O62– (in acidic solution)
