Which of the following statements is correct regarding the cathode of electrochemical cell ?

Step-by-step solution

In any electrochemical cell, whether galvanic or electrolytic, reduction always takes place at the cathode. Oxidation always takes place at the anode. The cathode is made of a conducting material to allow the flow of electrons. In a galvanic cell, the cathode is denoted by a positive sign, whereas in an electrolytic cell, it is denoted by a negative sign. Thus, the only universally correct statement is that reduction occurs at the cathode. Answer: Reduction occurs at cathode
