Distinguish between the following pair of compounds using the test given within bracket :
Sodium nitrate and sodium sulphite (using dilute sulphuric acid).

Explanation

To distinguish between sodium nitrate (NaNO3) and sodium sulfite (Na2SO3) using dilute sulfuric acid (H2SO4), we can follow these steps:

### Step 1: Reaction of Sodium Nitrate with Dilute Sulfuric Acid
1. Take a small amount of sodium nitrate (NaNO3) in a test tube.
2. Add dilute sulfuric acid (H2SO4) to the sodium nitrate.
3. Observe the reaction.

**Expected Result**: When sodium nitrate reacts with dilute sulfuric acid, it produces colorless vapors of nitric acid (HNO3) along with sodium sulfate (Na2SO4).
