Question

Differentiate between true solution, colloids, and suspension

Answer 1

True Solutions	Colloids	Suspension
A true solution is a homogeneous mixture. The particles of a true solution cannot be distinguished from the solvent particles. The size of solute particles is less than 1nm. Particles of true solutions do not scatter light passing through it. Particles of true solution do not settle down at the bottom when left undisturbed. The particles of true solution cannot be separated by physical processes, like filtration etc.	A colloid is a heterogeneous mixture. The particles of a colloid are too small to be individually seen by naked eyes. The size of colloidal particles lies between 1nm to 1000nm. Colloids are big enough to scatter a beam of light passing through it and make its path visible. They do not settle down when left undisturbed They cannot be separated from the mixture by the process of filtration.	Suspension is a heterogeneous mixture. The particles of a suspension can be seen by the naked eye. The size of suspended particles is more than 1000nm. The particles of a suspension scatter a beam of light passing through it and make its path visible. The solute particles settle down when a suspension is left undisturbed, that is, a suspension is unstable. They can be separated from the mixture by the process of filtration.
