Question

A mixture of sand and water can be separated by the method:

• A. sedimentation followed by decantation
• B. filtration
• C. evaporation
• D. sublimation

Answer 1

Answer: (A), (B)

filtration
sedimentation followed by decantation

Sedimentation and decantation method is used for the separation of a mixture in which one component is a liquid and the other is an insoluble solid heavier than liquid.

Thus, a mixture of sand and water can be separated by combined sedimentation followed by decantation. It can also be separated by filtration.

Hence, the correct options area $\text{A}$ and $\text{B}$
