**Notes on Balancing the Half-Reaction:**
1. **Identify the changes in oxidation states:** Determine which atoms are oxidized and which are reduced.
2. **Separate the half-reactions:** Write down the oxidation and reduction half-reactions separately if needed.
3. **Balance atoms other than O and H:** Start by balancing atoms that are not oxygen or hydrogen.
4. **Balance Oxygen atoms:** Add \( \mathrm{H_2O} \) molecules to balance oxygen atoms.
5. **Balance Hydrogen atoms:** Add \( \mathrm{OH^-} \) ions to balance hydrogen atoms, noting the medium is basic.
6. **Balance the charges:** Ensure that the charges on both sides of the half-reaction are equal, adding electrons \( (e^-) \) where necessary.
7. **Combine the half-reactions if applicable:** Make sure the number of electrons gained in the reduction half-reaction equals the number lost in the oxidation half-reaction and combine them if required.
