Question

Arrange the following steps in a proper sequence for the separation of a mixture of kerosene and water.

(A) The mixture is kept standstill.

(B) The liquid mixture is taken in a separating funnel.

(C) The heavier component is first collected by opening the stop lock.

(D) Clear layers of the liquids are formed and the heavier liquid that is water forms the bottom layer.

• A. B,A,D,C
• B. B,C,A,D
• C. B,C,D,A
• D. A,D,C,B

Answer 1

The correct option is A

B,A,D,C

The explanation for the correct option:

Immiscible liquids are defined as liquids that do not mix and form two distinct layers. The two liquids are separated using a separating funnel. Depending on their densities, it will split the immiscible liquids into two different layers. The lower layer is made up of the heavier liquid, while the upper layer is made up of the lighter liquid. Because kerosene has a lesser density than water, it forms the top layer.

So, first; the liquid mixture is taken in a separating funnel then the mixture is kept standstill, clear layers of the liquids are formed and the heavier liquid that is water forms the bottom layer and thus the heavier component is first collected by opening the stop lock.

Conclusion: Hence, option (a) is correct that is B,A,D,C.
