Question

Classify solutions based on the particle size of the solute.

Answer 1

Definition of Solution:

A solution is a homogeneous mixture of two or more substances. A solution has a solvent and a solute as its components.

Based on the particle size of the solute, the solutions are divided into three types namely:

1. True solutions: It is a homogeneous mixture that contains small solute particles that are dissolved throughout the solvent.
   Example: A solution of sugar in water is solid in a liquid solution. In this solution, sugar is the solute and water is the solvent.
2. Colloidal solutions: It is a heterogeneous mixture made up of two phases namely, the dispersed phase and the dispersion medium. The substance distributed as particles is called the dispersed phase. The continuous phase in which the colloidal particles are dispersed is called dispersion medium.
   Example: The mixture of milk powder containing fat, vitamin, protein, and water forms a colloid.
3. Suspensions: A suspension is a heterogeneous mixture in which small particles of a solid remain suspended throughout the mass of the liquid or gas.
   Example: Muddy water, sand-water mixture, chalk-water mixture, paints, etc., are suspensions.
