Question

A separating funnel can be used to separate a mixture of:

• A. Sugar and water
• B. Water and kerosene
• C. Salt and water
• D. Kerosene and petrol

Answer 1

The correct option is B Water and kerosene

A separating funnel is used to separate the mixture of two immiscible liquids with varying densities. Immiscible liquids are those which do not mix with each other and form distinct layers. Among the given options, water and kerosene are immiscible liquids.

During the process of separation, the mixture of kerosene and water is allowed to standstill in a separating funnel. Oil being lighter compared to water, floats on it. The water is then drained out from the bottom of separating funnel and oil remains inside it.
