Which separation technique will you apply for separating the following mixtures:

(i) Butter from curd.

(ii) Different pigments from extracts of flower petals

Answer :

(i) Butter from curd.

Centrifugation is the method of choice for separation of butter from curd. In this process the mixture is spun at a specific speed to differentiate the components. The principle is that denser particles are forced to the bottom and lighter particles stay at the top.


(ii) Different pigments from extracts of flower petals


Chromatography can be used for separation of pigments from extracts of plants. It is based on the difference in solubility of the pigments with the solute, which leads to differentiation.
