Question

Name a technique used to separate : Petrol and water

• A. distillation
• B. separating funnel
• C. sublimation
• D. chromatography

Answer 1

The correct option is B separating funnel

Use a separating funnel since the petrol floats above the water.Just let the mixture stand. Petrol and water are not soluble, so they will eventually separate. Since the petrol is lighter than the water, it will form a layer on top, and may be drawn off.Petrol will form at the top of water as it is not as heavy.
