Question

During electrosmosis of Fe(OH)3 Sol

A.)Sol particles move towards anode

B.)Sol particles move towards cathode

C.)Dispersion medium moves towards anode

D.) Dispersion phase move towards cathode

Answer 1

option(a) is correct.

Explanation:

Electro osmosis is the process in which under an applied electric field, colloidal particles movement is prevented and the dispersion medium only moves.
As the ferric hydroxide sol is positive colloid, the sol particle moves towards the cathode. As per the electro osmosis the sol particle movement is prevented and the dispersion medium moves in the opposite direction. So they move towards the anode.
