Question

Which of the following statements is universally correct regarding the polarity and function of electrodes in electrochemical cells?

Answer: B

💡 Solution & Explanation

By convention, the anode is strictly defined as the electrode where oxidation takes place, and the cathode is where reduction takes place. In a galvanic cell, the anode is negative, but in an electrolytic cell, the anode is positive. Thus, polarity is not a universal identifier, but the half-reaction type is.
