Question

What is colloidal solution?? class 9​

Answer 1

$\bf \huge \mathfrak \pink{Answer}$

A colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspensions. For Example: - Soap solution, Milk, Ink, Blood and solutions of synthetic detergents.

Answer 2

COLLOIDAL SOLUTION -

• A Solution in which the dispersed phase is mixed in dispersing medium.
• The particle size in colloidal solution ranges from 1 - $10^-^9$metre.
• In colloidal solution, the particles of the dispersed phase remain in a suspended manner.
• The substance that is dispersed is known as the dispersion phase and in which it is dispersed is known as the dispersion medium.
• On the basis of physical state colloidal solutions can be Solid solutions, aerosols, gels, Emulsions.
• Based on dispersion medium, solutions can be alcosol, hydrosol, and acrosol.
• Based on interactive forces between the dispersed phase and dispersion medium are lyophilic and lyophobic sol.
• Example - Mud, milk, jelly, cream, dust, cheese, butter, smoke.
