Balancing Redox Equations

Read each question carefully and balance the following redox equations using the half-reaction method. Show all your work for full credit.

1. Balance the following redox reaction in acidic solution:

MnO₄⁻(aq) + C₂O₄²⁻(aq) → Mn²⁺(aq) + CO₂(g)

2. Balance the following redox reaction in basic solution:

Cr(OH)₃(s) + ClO⁻(aq) → CrO₄²⁻(aq) + Cl⁻(aq)

3. In a redox reaction, the species that loses electrons is said to be  , and it acts as the   agent.

4. The species that gains electrons is said to be  , and it acts as the   agent.

5. Which of the following is true for an oxidation half-reaction?

6. In balancing redox reactions in basic solution, H⁺ ions are added to balance hydrogen atoms, followed by OH⁻ ions.
