Solution

Property True Solution Colloidal Solution

Size of the particles < 1nm 1 – 100 nm

Nature Homogeneous Heterogeneous

Tyndall effect True Solution does not show Tyndall effect. Colloidal solution shows Tyndall effect.

Separation Cannot be done by filtration Separation of colloidal solution cannot be done by filtration. However, it is possible by centrifugation process.
