Consider the following diagram in which an electrochemical cell is coupled to an electrolytic cell. What will be the polarity of electrodes 'A’ and ‘B’ in the electrolytic cell?
The cell drawn above represenis electrochemical cell in which two different electrodes are fitted in their respective electrolytic solution and cell drawn at bottom represents electrolytic cell. ,
Cell representation can be represented as Zn | Zn2+ || Cu2+ | Cu
Zn is loosing electrons which are going towards electrode (A) and copper is accepting electron from electrode B. Hence,
Charge on electrode A = + Charge on electrode B = —
