प्रश्न
Common salt from a solution of common salt in water
- Give the principle involved in the separation of the mixture
- Give the technique of separation of the mixture.
उत्तर
By Evaporation
Principle – Based on the evaporation of the liquid component in a soluble solid-liquid mixture.
Evaporation – It is a method used for recovery of the soluble solid from a solution by heating the mixture slowly, in a porcelain crucible on a flame.
For smoother steady heating the porcelain crucible may be kept in a sand bath [a shallow metallic dish filled with sand].
The 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. The liquid component is lost to the atmosphere The soluble solid component remains behind in the evaporating dish
