Question

Write the differences between miscible and immiscible liquids with example.

Answer 1

Hint: Miscibility means capability of mixing with water. Understand about mutual solubility and try to differentiate between miscible and immiscible solutions accordingly.

Complete Solution :
To answer this question, firstly let us understand what miscible and immiscible liquids are:
- Miscible liquids are liquids which have the ability to mix with each other without any chemical reaction needed but physical reaction is required. Miscibility refers to the ability of a liquid to completely dissolve in another liquid solution. There will be no formation of layer between two liquids in miscible liquids.
For instance, when water and some organic acids are mixed, two layers remain, but the layer with water contains some acid and the layer with acid contains some water.
- Immiscibility is the property where two substances are not capable of combining to form a homogeneous mixture. Components of an immiscible mixture will separate from each other. The less-dense fluid will rise to the top and the component with higher density will sink to the bottom.
- Now, let us differentiate between miscible and immiscible liquids:

Miscible liquids	Immiscible liquids
Liquids which mix together in all proportions and form a single layer are called miscible liquids.	Liquids which do not mix with each other and form separate layers are called immiscible liquids.
They are separated by the process of fractional distillation.	They are separated by separating funnels.
Some examples of Miscible solutions include water and organic compounds such as alcohols, aldehydes and ketones.	Immiscible solutions include water and many types of oils. Oil and water make an immiscible liquid.

We can understand the difference between miscible and immiscible solutions and their examples from the above table and this is the required answer.

Note: In any proportion, alcohol and water will mix to form a homogeneous solution. Liquids have their boiling points above room temperature, under normal conditions. A heterogeneous mixture is a mixture where two immiscible phases of two solutions are present in one.
