Balancing Oxidation-Reduction Reactions

Balancing Oxidation-Reduction Reactions

Read each question carefully and balance the oxidation-reduction reactions as instructed. Show all your work for full credit.

1. Oxidation is the   of electrons, while reduction is the   of electrons.

2. An oxidizing agent is the species that gets  , and a reducing agent is the species that gets  .

Balance the following redox reaction in acidic solution:

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

Balance the following redox reaction in basic solution:

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

1. In the reaction: Zn(s) + Cu²⁺(aq) → Zn²⁺(aq) + Cu(s), which species is being oxidized?

1. In a redox reaction, the number of electrons lost must equal the number of electrons gained.
