The cause of Brownian movement which is not shown by true solutions or suspensions is due to
A
(a) Unbalanced bombardment of particles by molecules of the dispersion medium
A
(b) Attractive forces between dispersed phase and dispersion medium
A
(c) Larger size of the particles due to which they keep colliding and settling down
A
(d) Conversion currents formed in the sol.
Explanation
Solution
(a)
Sol. The colloidal particle are in a continuous zig-zag motion due to unbalanced bombardment of the particles by molecules of the dispersions medium.
