You are provided with solutions of sodium hydroxide and ammonium hydroxide. How would you identify each cation in the following pairs of cations which are provided in separate test tubes as solutions?
`Pb^(2+)` and `Fe^(3+)`

Explanation

To identify the cations \( \text{Pb}^{2+} \) (lead) and \( \text{Fe}^{3+} \) (iron) in separate test tubes using sodium hydroxide (NaOH) and ammonium hydroxide (NH₄OH), follow these steps:

### Step-by-Step Solution:

1. **Identify the Test Tubes**: You have two test tubes, one containing \( \text{Pb}^{2+} \) and the other containing \( \text{Fe}^{3+} \).

2. **Test for \( \text{Fe}^{3+} \)**:
- Take the test tube that you suspect contains \( \text{Fe}^{3+} \).
