A true solution (simply a solution) shows the following characteristics.
(i) A true solution (or simply a solution) is a homogeneous mixture. That is in a true solution, the solute and solvent molecules cannot distinguish even under microscope. The composition and properties of a true solution are the same throughout.
(ii) In a true solution, the solute particles are very small, of the order of about 10 -10 m.
(iii) A true solution is clear and transparent.
(iv) A true solution does not scatter light.
(v) The components of a true solution (the solute and the solvent), cannot be separated by filtration. This is because both solute particles and the solvent molecules are very small as compared to the pores in the filter paper.
(vi) The solute particles in a true solution do not settle down.
