Question

State the principle for separation of immiscible liquids.

Answer 1

Hint : A liquid is a nearly incompressible fluid that conforms to its container's shape while maintaining a constant volume regardless of pressure. It is one of the four fundamental states of matter, and the only one with a fixed volume but no fixed shape.

Complete Step By Step Answer:
Miscibility is the ability of two substances to mix in any proportion (i.e., to fully dissolve in each other at any concentration), resulting in a homogeneous mixture (a solution). The term is most commonly used to describe liquids, but it can also be used to describe solids and gases. Water and ethanol, for example, are miscible because they mix in all proportions.
When two immiscible liquids (oil and an aqueous phase) are agitated, a system with dispersed liquid droplets in a continuous liquid phase is created. Solvent extraction units frequently create this situation because interphase mass transfer requires a large interfacial area between the two immiscible liquid phases.
In a separating funnel, immiscible layers separate into layers based on their densities. Consider the following scenario: A separating funnel can be used to separate kerosene oil and water.
The separating funnel is filled with a mixture of kerosene oil and water.
Allow it to sit undisturbed for a while to form separate layers of oil and water.
Open the separating funnel's stopcock and carefully pour out the lower layer of water.
As soon as the oil reaches the separating funnel's stopcock, close it.

Note :
Immiscible Metals cannot form alloys with each other. In the molten state, a mixture is usually possible, but when the metals freeze, they separate into layers. This property allows solid precipitates to form when a molten mixture of immiscible metals is rapidly frozen. Copper and cobalt are examples of immiscibility in metals, where rapid freezing to form solid precipitates has been observed.
