How will you distinguish between ferrous and ferric salts?

Explanation

To distinguish between ferrous (Fe²⁺) and ferric (Fe³⁺) salts, we can perform a simple test using sodium hydroxide (NaOH). Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Prepare Solutions:**
- Take two separate test tubes. In one test tube, add a few drops of ferrous salt solution (e.g., ferrous sulfate, FeSO₄).
- In the other test tube, add a few drops of ferric salt solution (e.g., ferric sulfate, Fe₂(SO₄)₃).
