Explain the following observations:
(a) Cottrell’s smoke precipitator is fitted at the mouth of the chimney used in factories.
(b) Physical adosption is multi layered, while chemisorption non-tayered.
When electric potential is applied across two palantium electrodes across two plantium electrodes depping in colloidal solution, the movement of colloidal particles move towards one or other electrode.
Positively charged particles move towards the cathode while negative charged particles moves towards the anode.
