Answer 1

Answer:

we can separate the mixture of ammonium chloride and salt through sublimation process. The process by which the change of gaseous state directly to solid state without going through liquid state, and vice versa.

Explanation:

• Take a tripod stand and place wire gauze on it.

• Place a china dish on the wire gauze.

• The mixture must be taken it the china dish.

• It must be covered with a glass funnel in an inverted position.

• The upper end of the funnel must be closed with cotton plug.

• Switch on the Bunsen burner.

• As mixture is heated, ammonium chloride gets released in form of gas and gets collected in the funnel whereas the salt remains in the dish.

Answer 2

Answer:

Ammonium chloride is a compound which sublimates ( Changes directly into gas from solid on less heating) but sodium chloride does not has this property.

Explanation:

The mixture of salt and ammonium chloride is kept in a China dish and it is kept over Bunsen burner. A flask is inverted over the mixture and the mixture is heated, the ammonium chloride sublimes and the salt is left behind. To recover the ammonium chloride, collect it in other China dish fro the walls of flask
