Give —
(a) the principle involved in separation of the mixture
(b) the technique of separation
for common salt from a solution of common salt in water.
Answer
(a) Principle involved: Based on evaporation of the liquid component in a soluble solid-liquid mixture.
(b) Technique of separation: The soluble solid can be separated from its liquid component by allowing the liquid component to evaporate either on its own or by heating. On heating, water is lost to the atmosphere and common salt remains behind in the evaporating dish.
