Balance the equation in basic medium
`Al + NO_(3)^(-) to Al(OH)_(4)^(-) + NH_(3)`

Explanation

To balance the given redox reaction in basic medium, we will follow a systematic approach. The reaction we need to balance is:

\[ \text{Al} + \text{NO}_3^{-} \rightarrow \text{Al(OH)}_4^{-} + \text{NH}_3 \]

### Step 1: Identify Oxidation and Reduction Half-Reactions

1. **Oxidation Half-Reaction**:
- Aluminum (Al) is oxidized from an oxidation state of 0 to +3.
