Answer
This statement is incorrect. In a galvanic cell, reduction occurs at the positive electrode, known as the cathode. The negative electrode is the anode, where oxidation occurs.
Step 2
B. in both cells the anode is positive and the cathode is negative.

Answer
This statement is incorrect. In a galvanic cell, the anode is negative, while in an electrolytic cell, the anode is positive. Therefore, this statement does not hold true for both types of cells.
Step 3
C. in an electrolytic cell oxidation occurs at the cathode.
