Question

Particles of true solution are visible to the naked eye.

• A. True
• B. False

Answer 1

The correct option is B False

Property	True Solution	Colloidal Solutions	Suspension
Size of the particles	$<1nm$	$11000nm$	$>1000nm$
Nature	Homogeneous	Heterogeneous	Heterogeneous
Filterability Diffusion through parchment paper	Particles of true Solution diffuse rapidly through filter paper as well as parchment paper.	Colloidal particles pass through filter paper but not through the parchment paper.	Suspension particles do not pass through filter paper and parchment paper.
Visibility	Particles of True Solution are not visible to the naked eye.	Colloidal particles are not seen by the naked eye but can be studied through an ultramicroscope.	Suspension particles are big enough to be seen by the naked eye.
Tyndall effect	True Solution does not show Tyndall effect.	Colloids show the Tyndall effect.	Suspension may or may not show the Tyndall effect.
Appearance	Transparent	Translucent	Opaque
