Difference between true solution, suspension and colloids?

Answer

 

True Solution

Suspension

Colloids

A true solution is a homogeneous mixture of solute and solvent.

A Suspension is a heterogeneous mixture

A colloidal solution appears to be homogeneous but actually it is a heterogeneous mixture of solute and solvent.

A true solution is transparent.

Suspension is Opaque.

Colloids are translucent.

The solute particles are very small, less than 1nm.

The solute particles are large and visible, more than 100nm.

The solute particles are between the range 1-100 nm.

The solute particle does not show Tyndall effect.

The particles may or may not show Tyndall effect.

The particles show Tyndall effect.

The particles do not settle due to gravity, e.g, salt in water solution.

The particles may settle due to gravity, e.g, chalk powder in water.

The particles do not settle due to gravity, e.g, blood.
