Which of the following properties of colloid is used to measure the rate of migration of sol particles?

Step-by-step solution

Electrophoresis is the phenomenon of movement of colloidal particles under the influence of an applied electric field. By observing this movement, the rate of migration of sol particles can be measured. Tyndall effect is the scattering of light by colloidal particles. Brownian motion is the continuous zig-zag motion of colloidal particles. Electroosmosis is the movement of the dispersion medium under an electric field when the colloidal particles are prevented from moving.
