1.	Identify the false statement among the followingA. Oxidation takes place at positive electrode in electrolytic cell, whereas reduction at negative electrode in voltaic cellB. Deposition of metals takes place in both electrolytic and galvanic cellsC. Direction of flow of current is from cathode to anode in electrolytic cellsD. Both a and b
Answer» In an electrolytic cell, the direction of flow of electrons is from cathode to anode and hence the flow of current is taken in opposite direction from anode to cathode.
