Question

How does the particle size vary in a true solution a suspension and a colloid?

Answer 1

The particle size of true solution is very small (1 nm). The particle size of suspension is comparitively larger(upto 100nm). The particle size of colloid is between size of true solution and suspension

Answer 2

True solution.
_homogeneous mixture
_particle size less than 1u
_can't be seen by naked eyes even by ultra microscope
colloidal solution
_heterogeneous mixture
_particle size between 1u and 100u i.e between true sollution and suspension
suspension
_heterogeneous mixture
_particles are suspended in solvent
_particle size more than 100u
if satisfied
