$C$

Vedclass · Answer

(C) The $Fe(OH)_3$ sol is a positively charged colloid. In the presence of an electric field,the dispersion medium (water) moves towards the cathode due to electro-osmosis. Since container $C$ is connected to the cathode (negative electrode),the water will move through the semi-permeable animal membrane $S$ from container $B$ into container $C$. Therefore,the water level in container $C$ will increase.

If $Fe(OH)_3$ sol is filled in container $B$,then water level in which container will increase?
