Sol.

Only polar compounds dissolve in water.

When nonpolar compound is mixed with water it gets precipitated.

We are given a mixture of naphthalene and Ammonium chloride.

We  know that naphthalene is a non-polar compound and ammonium chloride is a polar compound.

If you make water solution of the mixture of naphthalene and ammonium chloride, the naphthalene with precipitate and ammonium chloride will dissolve.

So by the process of decantation, using funnel and filter paper, we can separate naphthalene.

Ammonium chloride is volatile at higher temperature. Hence, by the process of evaporation we can find out dry ammonium chloride from aqua solution.
