Question

student is given a mixture of naphthalene ball’s powder and common salt. He need to

separate this mixture. How will he do this?​

Answer 1

Explanation:

A student is given a mixture of naphthalene ball's powder and common salt. ... 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.

Answer 2

Answer:

We know that naphthalene directly changes from solid to gaseous form without going into the liquid form. This means that it is a volatile substance. we can use the method of sublimation to separate the mixture. Since salt is less volatile as compared with naphthalene balls, we can easily separate it by heating the mixture. After a moment naphthalene balls will disappear and only salt will be left.
