The colloidal solutionis the solution that has a particle size ranging from true solutions and suspensions. The range of the diameter of the dispersed particle is from 10 Angstrom to … See more WebA process of converting a precipitate into colloidal sol called Peptization by shaking it with the dispersion medium. Colloidal solutions of the hydroxides of Fe, Cr, Al etc can be prepared by hydrolysis of their salts. In ultrasonic dispersion, ultrasonic waves are passed through the solution containing larger particles.
