Give the chemical tests between the following pairs:
A lead salt and a zinc salt.

Explanation

To distinguish between a lead salt and a zinc salt, we can perform a chemical test using ammonium hydroxide (NH₄OH). Here’s a step-by-step solution:

### Step 1: Prepare the Solutions
- Take a small amount of the lead salt solution (e.g., lead(II) nitrate, Pb(NO₃)₂) and a small amount of the zinc salt solution (e.g., zinc sulfate, ZnSO₄).

### Step 2: Add Ammonium Hydroxide
- To both solutions, add a few drops of ammonium hydroxide (NH₄OH) solution.
