Question

Which separation process is used to recover both solute and solvent from a solid-liquid solution?

• A. Distillation
• B. Sublimation
• C. Evaporation
• D. Separating funnel

Answer 1

The correct option is A

Distillation

In order to recover both the solute and the solvent from a solution, the process of distillation has to be used. It is a process in which evaporation and condensation go on side by side. When the solution is heated, the solvent evaporates, leaving behind the solid. Vapours of the solvent are condensed to give the liquid, which is called the ‘distillate’.

Evaporation is used to get only the solid component from a solid-liquid mixture.

Sublimation is used to separate solid-solid mixtures in which one of the solid components is volatile.

A separating funnel is used to separate two immiscible liquids.
