![**Balancing Redox Reactions Using the Half-Reaction Method**
Use the half-reaction method to balance the following equation in acidic solution. It is not necessary to include any phases of matter for any species.
\[ \text{CN}^- + \text{MnO}_4^- \rightarrow \text{CNO}^- + \text{MnO}_2 \]
This exercise involves balancing a chemical equation by separating it into two half-reactions—one for oxidation and one for reduction. In this particular equation, cyanide (\(\text{CN}^-\)) undergoes oxidation, and permanganate (\(\text{MnO}_4^-\)) is reduced. Follow these steps to achieve a balanced equation:
1. Write separate half-reactions for the oxidation and reduction processes.
2. Balance each half-reaction for all elements except hydrogen and oxygen.
3. Balance oxygen atoms by adding water (\(\text{H}_2\text{O}\)).
4. Balance hydrogen atoms by adding hydrogen ions (\(\text{H}^+\)).
5. Balance the charge by adding electrons (\(e^-\)).
6. Equalize the number of electrons transferred in each half-reaction.
7. Add the balanced half-reactions together, ensuring that electrons cancel out.
8. Verify that the atoms and the charges are balanced in the final equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faed2933e-b67f-42a0-9fac-b6dce0e828b0%2F7c33602b-444d-4d4d-afb0-047b3bd0dd74%2Ff9mebxo_processed.jpeg&w=3840&q=75)
