Name the technique to separate butter from curd, salt from sea water and camphor from salt.

Name the technique to separate

(i) butter from curd,

(ii) salt from seawater,

(iii) camphor from salt.

Answer:

i) Name the technique to separate butter from curd- CENTRIFUGATION

ii) Name the technique to separate Salt from seawater- EVAPORATION

iii) Name the technique to separate camphor from Salt- SUBLIMATION

Explanation:

Centrifugation: Centrifugation is accomplished by the use of a machine known as a centrifuge.

Concentration is a separation technique used to separate suspended particles from a liquid that involves rotating or spinning the mixture at a high speed in a centrifuge. Centrifugation is used to separate suspended particles from liquids.

Evaporation: It is necessary to employ evaporation to separate a solid substance once it has been dissolved in water or any other liquid.

This is due to the fact that liquids vaporize easily but solids do not vaporize easily, which makes the employment of the process of evaporation for separation a viable option.

Sublimation: Sublimation is defined as the transformation of a solid straight into vapors when heated, and the transformation of air vapor into solid when cooled.

Sublimation is a procedure that is used to extract those compounds from a combination that becomes sublime when it is heated.
