Suggest a method of separation for a mixture of sodium chloride and ammonium chloride. Explain the process.

Explanation

To separate a mixture of sodium chloride (NaCl) and ammonium chloride (NH4Cl), we can use the method of sublimation. Here’s a step-by-step explanation of the process:

### Step 1: Understand the Properties of the Mixture
- Sodium chloride (NaCl) is a non-sublimable substance, meaning it does not change directly from solid to gas upon heating.
- Ammonium chloride (NH4Cl), on the other hand, is a sublimable substance; it can transition from solid to gas when heated.

### Step 2: Prepare the Apparatus
- Set up a heating apparatus, such as a Bunsen burner or a hot plate.
