Answer 1

Answer: -

A mixture of ammonium chloride and potassium nitrate can be separated by sublimation.

Explanation: -

Ammonium chloride can sublime on heating. Sublimation is the process by which a substance changes from solid to gas without passing through the liquid phase.

Ammonium chloride on warming sublimes and later reforms into solid on cooler parts of the test tube.

The potassium nitrate is left behind.

Thus a mixture of ammonium chloride and potassium nitrate can be separated by sublimation.
