Question

Give five important points of differences between a true solution and a colloidal solution

Answer 1

Substances are classifies into true solution and colloidal solution depending upon the property of the substances

True solution	Colloidal solution
Solute particles dissolved in a solvent and form homogeneous mixture.	The particles are dispersed (dispersed phase) in a medium called dispersion medium, forms a heterogeneus mixture
The solute particles have size less than 1 nm	The dispersed particles have size 1-1000 nm size.
Particles do not settle down	Particles do not settle down, but can be forced to settle down using centrifugation
Particles do not show Tyndall effect	Particles show Tyndall effect (path of light visible when light passed through it due to scattering)
Example: sugar solution	Example: milk
