Question

Name the technique used to separate

(a) butter from curd,

(b) salt from sea-water,

(c) camphor from salt.​

Answer 1

Answer:

1. Centrifugation

2. Evaporation

3. Sublimation

Answer 2

Explanation:

a)centrifugation

The technique used to separate butter from curd is centrifugation.

b)distillation

This is good for separating a liquid from a solution. For example, water can be separated from salty water by simple distillation. This method works because the water evaporates from the solution, but is then cooled and condensed into a separate container. The salt does not evaporate and so it stays behind.

c)Sublimation

Sublimation is a technique used to separate the components of a mixture containing a sublimable volatile solid and a non-sublimable impurity. Therefore, the mixture of camphor and sodium chloride can be separated by the process of sublimation
