Question

The liquids which do not dissolve in water are called __(miscible/immiscible) liquids.

Answer 1

The liquids which do not dissolve in water are called immiscible liquids. E.g., petrol, diesel, mustard oil, etc.

Separating immiscible liquids is done simply using a separating funnel. The two liquids are put into the funnel and are left for a short time to settle out and form two layers. The tap of the funnel is opened and the bottom liquid is allowed to run. The two liquids are now separate.
