Question

Between filtration and decantation, which is a more efficient method of separating substances from a mixture? Explain why?​

Answer 1

Answer:

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.

Explanation:

In decantation, the mixture is left undisturbed for some time and then the liquid is poured in another vessel without disturbing the sediments. Whereas in case of filtration, the mixture is not left undisturbed for sediments to settle down. The mixture is just poured in a vessel through a filter paper.
