properties of a Solution
The important characteristic properties of a solution (or true solution) are as follows :
1.A solution is a homogeneous mixture.
2.The size of solute particles in a solution is extremely small. It is less than 1 nm in diameter (1 nanometre= metre).
3.The particles of a solution cannot be seen even with a microscope.
4.The particles of a solution pass through the filter paper. So, a solution cannot be separated by filtration.
5.The solutions are very stable. The particles of solute present in a solution do not separate out on keeping.
6.A true solution does not scatter light (This is because its particles are very, very small).
