Question

Decantation can be used to separate:

• A. heterogeneous solid-liquid mixtures
• B. heterogeneous and homogeneous solid-liquid mixtures
• C. homogeneous liquid-liquid mixtures
• D. None of the above

Answer 1

The correct option is A heterogeneous solid-liquid mixtures

Heterogeneous mixtures are insoluble in each other. This mixture can be separated by sedimentation followed by $Decantation$.

In this process first, the heavier particles are allowed to settle down by the process of sedimentation and then they are separated by the process of decantation.
Hence, option $A$ is the correct answer.
