State two properties of true solution

True solutions are homogenous solutions containing a mixture of two or more substances dissolved in a solvent. 
A true solution (simply a solution) shows the following property.

(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.
