What is a Solution?
A homogenous mixture of the materials in which the solute particle is dissolved evenly and the average size of the solute particles is less than 1 nm is called a solution. A solution has two components a solute and a solvent. The substance which is in lesser quantity and is generally solid or liquid is called a solute where as the solvent quantity is always greater and it is generally in the liquid state.
Properties of Solution
Various properties shown by the solutions are,
- Solution is a homogenous mixture i.e. all its solute particles are distributed evenly.
- Solution has particles with an average size of less than 1 nm in diameter.
- Naked eye is incapable of viewing the particles of the solution.
- Physical methods such as filtration and other are not capable of separating the solute particles from the solution.

Suspensions
Suspension is a heterogeneous mixture of a fluid that contains solute particles that are considerably large for the process of sedimentation. Suspensions are considered to be heterogeneous in nature because they contain at least two different substances. The particles in a suspension are easily visible to the naked eye. The particles are pulled down to the bottom of the container containing the dispersion medium (water). Some of the particles in the suspension sediment to the bottom when the mixture is left. However, suspensions are mixtures where the particles do not settle.
