what are the differences between a true solution, colloidal solution and suspension
(i) A true solution is a homogeneous mixture of two or more than two substances.
(ii) In a true solution, solute cannot be seen even with a microscope.
(iii) In a true solution, the size of particles is about 10-10 m.
(iv) The constituents of a true solution cannot be separated by filtration.
(i) A colloid is a homogeneous-looking, but heterogeneous-mixture.
(ii) In a colloid, the particles can be seen only with a powerful microscope.
(iii) In a colloid, the size of particle is between 10-7 10-9 m.
(iv) The constituents of a colloid cannot be separated by filtration.
(i) A suspension is a heterogeneous mixture of a solid dispersed in a liquid, or gas.
(ii) In a suspension, the particles can be seen with the naked eyes.
(iii) In a suspension, the size or particle is bigger than 10-7 m.
(v) The constituents of a suspension can be separated by ordinary filtration.
