Question

how will you separate a mixture of naphthalene balls powder and common salt with diagram

Answer 1

Naphthalene is a sublimate which on heating changes to gaseous state directly. Hence to separate a volatile compound (sublimate) from a non-volatile compound (non-sublimate), the sublimation process is used.

In a China dish the mixture is kept, and is placed on a stand. An inverted funnel is kept over the mixture in China dish with plugged stem. The sublimate on heating gets collected on the funnel and common salt remains in the China dish.

Answer 2

Answer: By Filtration & Evaporation Process .

Explanation:

First of all , Naphthalene is insoluble in water . So , dissolve mixture of salt and Naphthalene in Water . Separate Naphthalene through a filter paper . The salt solution obtained can be separated through process of Evaporation .
