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 `Ca^(2+)`

Explanation

To identify the cations \( \text{Pb}^{2+} \) (lead) and \( \text{Ca}^{2+} \) (calcium) using sodium hydroxide (NaOH) and ammonium hydroxide (NH4OH), follow these steps:

### Step-by-Step Solution:

1. **Prepare the Solutions**:
- You have two test tubes, one containing a solution of sodium hydroxide (NaOH) and the other containing ammonium hydroxide (NH4OH).

2. **Testing for Lead Ion (\( \text{Pb}^{2+} \))**:
...
