Question

What type of colloid is formed when a gas is dispersed in a liquid? Give an example.

Answer 1

Hint: Colloids contain two phases. When gas is dispersed in a liquid, the dispersed phase is gas and the dispersion medium is liquid.

Complete answer:
A colloid is a mixture in which a phase remains dispersed in the suspension. The size of colloidal particles varies from 1 to1000 nm. Due to the large size colloid solution contains the different phases of suspended particle and suspension medium.
The colloidal solution is of 8 types.
Solid in gas. The colloidal type is an aerosol.
Solid in liquid. The colloidal type is a sol.
Solid in solid. The colloidal type is a solid-sol.
Liquid in solid. The colloidal type is a gel.
Liquid in liquid. The colloidal type is an emulsion.
Liquid in gas. The colloidal type is a liquid aerosol.
Gas in solid. The colloidal type is a solid foam.
Gas in liquid. The colloidal type is a foam.
The colloidal solution of the gas in a liquid is known as the foam. Whipped cream, shaving cream, and beaten egg white are examples of the form.
On the basis of the physical appearance of the colloidal solution, the type of dispersion medium can be identified. The whipped cream, shaving cream and beaten egg white all are in liquid form.

Note: In the name of the colloid, the first word represents the dispersed phase and the second word represents the dispersion medium. Gas in liquid and liquid in gas both are different types of colloids.
