Question

How will separate water from petrol?​

Answer 1

Answer:

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.

Answer 2

Answer:

Using Separating Funnel , Petrol can be separated from water.

Petrol is the Lighter Liquid

Water is the Heavier Liquid

Explanation:

Separating Funnel is used for separating Immiscible Liquids.

Principle : The method works when two liquids are Immiscible. The heavier liquid forms the lower layer and the lighter liquid forms the upper layer.

Technique of Separation : The mixture is placed in a separating funnel. The mixture forms two layers after sometime - the lighter liquid forms the upper layer and the heavier liquid forms the lower layer. When the stopper of the Funnel is opened slowly, the heavier liquid comes out first and get collected in a Container. When the lower layer is transferred or drained completely, the stopper of the Funnel is closed. The lighter liquid remains in the Separating Funnel .
