Question

Which of the following mixtures could not be separated into its components by decanting?
A) Beans in hot water B) Sand in water C) Oil in water D) Coffee in hot water

Answer 1

{ D} coffee in hot water.

Answer 2

(D)."Coffee in hot water" mixtures could not be separated into its components by decanting.

Explanation:

• Decantation is the separation of liquid from solids and other immiscible (non-mixing) liquids by separating the liquid layer on top from the solid or liquid layer below. After pouring away the top layer, tilt the mixture to complete the procedure.
• Because sawdust is not heavier than water, sedimentation and decantation cannot be employed to separate it from water.
• Only if the solid is heavier than the liquid can sedimentation and decantation be employed to separate an insoluble solid from a liquid.
