Experiment for pure and impure naphthalene?
For a simple experiment to distinguish between pure and impure naphthalene, you can try sublimation. Place a small amount of naphthalene in a test tube and heat it gently. If the naphthalene sublimes (converts from solid to gas without melting), leaving no residue, it is likely pure. However, if there is residue left behind, it suggests the naphthalene is impure.
What will melt faster pure or impure naphthalene?
Impure naphthalene will typically melt faster than pure naphthalene. The impurities present in impure naphthalene lower its melting point, making it easier for the solid to convert into a liquid state at a lower temperature.

What is the solute and solvent of naphthalene on air?
In this context, the solute is naphthalene while the solvent is air. Naphthalene is the substance that is being dissolved in the air.
