3. Balance the following in basic solution: a. SO,? (aq) + Cu(OH), (s) So,? (aq) + Cu(OH) (s) b. O2 (g) + Mn(OH), (s) → MnO, (8) c. NO3 (aq) + H2 (g) d. Al (s) + Cro, (aq) – Al(OH), (s) + Cr(OH), (ag) + NO (9) 4. Identify the species that was oxidized, the species that was reduced, the oxidizing agent, and the reducing agent in each of the reactions of the previous problem. 5. Why is it not possible for hydroxide ion (OH") to appear in either of the half-reactions or the overall equation when balancing oxidation-reduction reactions in acidic solution? 6. Why is it not possible for hydrogen ion (H') to appear in either of the half-reactions or the overall equation when balancing oxidation-reduction reactions in basic solution? 7. Why must the charge balance in oxidation-reduction reactions?
