Naphthalene can be separated from sand :(a) by sublimation (b) by distillation(c) by crystallisation (d) by using water as solvent

Academic Chemistry NCERT Class 9

Correct Answer: (a) by sublimation

Explanation: Naphthalene sublimes on heating, whereas sand does not. So, when the mixture is heated, solid naphthalene turns into vapours, which can be condensed. Sand remains in the container.
