Question

Which method of separation could be better
than sedimentation or decantation? Give a
reason for your answer.​

Answer 1

Answer:

The larger and heavier solid particles settles down leaving the clear liquid above it. ... At the same time, during decantation, there is a chance of the particles mixing back in the liquid. Filtration technique can be used to overcome this as well. Thus, filtration is better than sedimentation and decantation.

Answer 2

Sedimentation is a process of separating large particles of solid from a mixture of solid and liquid under gravity, by leaving the mixture undisturbed for a long time.

The larger and heavier solid particles settles down leaving the clear liquid above it.

Thus, filtration is better than sedimentation and decantation.
