Question

Which of the following is used to separate a mixture of immiscible liquids?
(A) Centrifuge
(B) Condenser
(C) Separating funnel
(D) Distillation flask

Answer 1

Hint: The separation of immiscible liquids is done by leaving them for a short time to settle down as immiscible liquids don't mix with each other. Different liquids have different boiling points and that helps us to separate immiscible liquids.

Complete step by step solution:
Mixtures of liquids are separated on the basis of their properties. So this basically depends upon whether the mixture is immiscible or miscible.
Miscible liquid basically means that the two liquids mix with each other or we can say that they dissolve on each other.
Immiscible liquid basically means that these liquids do not mix with each other or we can say that they do not dissolve in each other. The most common example is oil in water. These liquids do not mix with each other even if we shake them vigorously, they mix for some time but as soon as we leave it for a short time they get separated again.
An immiscible liquid can be separated using a separating funnel. The immiscible liquid is placed in a separating funnel and is left undisturbed for some time to settle out. After some time there is a formation of two layers. After this, the tap of the funnel is opened and the liquid at the bottom is allowed to run and at the end, we get two separated liquids.

Hence the correct option is (C) separating funnels.

Note: It is important to leave the immiscible liquid undisturbed for some time and when the liquid at the bottom is allowed to run then take care of when to close the tap of the funnel.
