Question

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

Answer 1

Explanation:

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

Filtration is the best method compared to sedimentation and decantation.

Reason: Filtration can separate very fine insoluble particles as compared to the other two methods.
