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?

Text Solution

Verified by Experts

In the electrochemical cel, zinc acts as a negative pole while copper acts as a positive pole. Hence, electrode 'A' will have negative polarity while electrode 'A' will have positive polarity.
