Question

. The Brownian movement in colloids is due to:
a. Tyndall effect
b. Charge on colloidal solution
C. Collisions between the colloidal particles and the dispersion medium
d. All of the above.​

Answer 1

Answer:

Brownian movement arises because of the impact of the molecules of the dispersion medium with the colloidal particles. Since the impacts of the molecules of the dispersion medium on the colloidal particles are unequal (i.e. unbalanced bombardment), the result is zig-zag motion
