Question

If a mixture can be separated using both sedimentation-decantation and filtration, then which method would people generally prefer. Why?

Answer 1

Answer:

Filtration

Explanation:

Decantation is not the best method as there is a chance that while you are separating the mixture some of the unwanted substance will come out as well. The same goes for sedimentation.

With filtration there is no chance that both the substances will come out together unless the filtration paper tears.

Answer 2

Answer:

Filtration

 

Explanation:

As sedimentation and decantation takes longer and sometimes the substance that is unwanted may come out in sedimentation and decantation.
