Question

Name the method used for the separation of Ammonium chloride from a mixture containing Sodium chloride and Ammonium chloride.

Answer 1

Separation of mixtures:

• The process of separation of different constituents of a mixture using physical methods is known as the separation of mixtures.

The separation of the mixture of Ammonium chloride $\left({\mathrm{NH}}_4\mathrm{Cl}\right)$ and Sodium chloride $\left(\mathrm{NaCl}\right)$ :

Sublimation:

• The process of separating the mixture of Ammonium chloride and Sodium chloride is sublimation.
• In this process a sublimate substance changes its state from solid to gas directly without passing through a liquid state on heating.
• In this mixture of Ammonium chloride and Sodium chloride, Ammonium chloride is a sublimate so it gets changed into vapor and can be separated in another container.
• Sodium chloride will be left behind in the container.
• After cooling the vapor of Ammonium chloride, we get it in its original solid state..

Conclusion:
Therefore, Ammonium chloride is$\left({\mathrm{NH}}_4\mathrm{Cl}\right)$is separated from a mixture of Ammonium Chloride and Sodium chloride$\left(\mathrm{NaCl}\right)$ by the process of Sublimation.
