Question

What methods would you use to separate a mixture of camphor, salt and sand?

• A. Winnowing, chromatography, evaporation
• B. Sublimation, sedimentation, evaporation
• C. Evaporation, hand-picking, sublimation.
• D. Sedimentation, distillation, sublimation

Answer 1

The correct option is B

Sublimation, sedimentation, evaporation

First, the camphor can be separated from the mixture by sublimation. Then we mix the mixture with water and allow to stand. Sand settles down and can be separated from the salt solution by sedimentation and decantation. The salt can be obtained from the salt solution by evaporation.
