To separate a mixture of ammonium chloride (NH4Cl) and sodium chloride (NaCl), you can follow the following steps:

1. Dissolution: Add water to the mixture to dissolve both ammonium chloride and sodium chloride. Stir the mixture well to ensure complete dissolution.

2. Filtration: Once the mixture is dissolved, use a filter paper and a funnel to separate the solid particles from the liquid. The solid residue left on the filter paper will contain both ammonium chloride and sodium chloride.

3. Evaporation: Transfer the liquid obtained from filtration into an evaporating dish. Heat the dish gently to allow the water to evaporate. As the water evaporates, the ammonium chloride and sodium chloride will start to crystallize.

4. Separation: Once the evaporation is complete, you will be left with a mixture of ammonium chloride and sodium chloride crystals. To separate them, you can use the difference in solubility between the two compounds. Add a small amount of water to the mixture and stir. Ammonium chloride is more soluble in water than sodium chloride, so it will dissolve while sodium chloride remains as solid crystals.

5. Filtration (again): Use a filter paper and a funnel to separate the solid ammonium chloride solution from the remaining sodium chloride crystals. The filtrate will contain the dissolved ammonium chloride.

6. Recovery: To obtain pure ammonium chloride, you can further evaporate the filtrate obtained in step 5. As the water evaporates, ammonium chloride crystals will form.

By following these steps, you can successfully separate a mixture of ammonium chloride and sodium chloride.
