Question

Do the colloidal particles settle on centrifugation?

• A. True
• B. False

Answer 1

The correct option is A True

Colloids

• The colloidal particles have size between 1-1000 nm.
• The collidal particles which dispersed in a medium are called dispersed phase and the medium in which particles are dispersed is called dispersion medium.
• The particles do not settle down when left undisturbed.
• But during centrifugation, where the dense particles are allowed/forced to move down and make the particles settle on centrifugation.

Therefore, the given statement is true, i.e.., the colloidal particles settle on centrifugation.
