Question

1) Ammonium chloride and salt separated by​

Answer 1

Explanation:

A mixture of ammonium chloride and common salt can be separated using sublimation. ... On heating the mixture, ammonium chloride changes into white vapours. These vapours rise up and get converted into solid ammonium chloride on coming in contact with the cold, inner walls of the funnel.

Answer 2

Answer:

Through the process of sublimation.

Explanation:

Sublimation is the process by which we can separate a mixture. In this mixture, there will be one component which will evaporate directly from solid to gas.

Process :

→ Make a mixture of ammonium chloride and salt in a china dish.

→ Place a closed funnel above the china dish.

→ Heat the mixture using a burner.

→ We will be left with the salt after sufficient heating.

→ Now, let the whole experiment cool for some time.

→ You will see solid ammonium chloride sticking to the walls of the funnel.
