Question

Petrol and water can be separated by ............ because................

• A. fractional distillation, they are immiscible liquids
• B. simple distillation, their boiling points slightly differ.
• C. separating funnel, they are immiscible liquids.
• D. None of these

Answer 1

Answer: (C)

separating funnel, they are immiscible liquids.

Separating funnel is used to separate immiscible liquids. Since petrol and water are immiscible, we can separate them using separating funnel.

Simple distillation is used to separate homogeneous mixtures that differ in their boiling points. Fractional distillation is based on the same principle, but it is generally used to separate mixtures whose boiling points differ by less than 25 K.

So, option C is correct.
