Question

Describe another method other than filtering to separate a solid from a liquid. Compare and contrast this method with filtering.

Answer 1

Centrifugation:

This method makes use of a centrifuge to separate mixtures of liquids and very fine solid particles, especially in cases where filtration does not work well. The centrifuge spins the mixture at very high speeds. This causes the denser particles of the solid to move outward and separate from the liquid. When the rotation is stopped, the solid particles end up at the bottom of the glass with the liquid at the top, which can be decanted.

Filtration	Centrifugation
Effective method to separate Larger solid particles.	Effective method to separate fine solid particles.
Applicable to heterogeneous mixture	Applicable to heterogeneous mixture
Fine solid particles can penetrate through pores of filter paper.	Fine solid particles could be deposited effectively.
No need for decantation	mother liquor shuold be decanted
Interposingmedium will be there(filter paper)	No Interposingmedium will be there
