Solution :
A solution is a homogeneous mixture of two or more substances.
The particles of a solution are smaller than 1 nm (10-9 metre) in diameter. So, they cannot be seen by naked eyes.
Due to small particle size, they do not scatter a beam of light passing through them. Thus, the path of light is not visible in a solution.
The solute particles do not settle down when left undisturbed, i.e., a solution is stable.
The solute particles cannot be separated from the mixture by the process of filtration.
Sol:
A sol is a heterogeneous mixture.
The size of particles of a sol is too small to be individually seen by naked eyes. It is between 1 nm and 100 nm in diameter.
Sols are big enough to scatter a beam of light passing through them and make its path visible.
They do not settle down when left undisturbed, i.e., a sol is quite stable.
The solute particles cannot be separated from the mixture by the process of filtration.
Suspension :
Suspension is a heterogeneous mixture.
The particles of a suspension can be seen by the naked eye. Their size is larger than 100 nm in diameter.
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, i.e., a suspension is unstable.
They can be separated from the mixture by the process of filtration.
