Question

Definition of true solution suspension and colloid

Answer 1

True solution- a true solution is a homogenous mixture of two. A homogenous mixture means that the mixture is just the same throughout. Example, salt solution, vinegar etc
a True solution doesn't scatter light.

Suspension- a suspension is a heterogeneous mixture in which the small particles of a solid are spread throughout a liquid dissolving in it.
Example, Chalk-water mixture etc
suspension scatter beam of light.

Colloids- A colloids is a kind of solution in which the size of solute particles is intermediate between those in true solution and those in suspension.
Example, milk,ink, blood etc.
A colloid scatter a beam of light.

Answer 2

Collidal solution is a heterogenous mixture in which particle size of substance is intermidatevof true solution and suspension between 1-1000nm.Just like true solution collidal particles are small enough and cannot be seen through naked eye .
