January 2020 Ny Regents Chemistry Exam
45 When comparing voltaic cells to electrolytic cells, oxidation occurs at the (1) anode in both types of cells
(2) cathode in both types of cells
(3) anode in voltaic cells, only
(4) cathode in voltaic cells, only
Solution: For both voltaic and electrolytic cells, oxidation occurs at the anode. A good mnemonic to memorize for the electrochemistry chapter is : Red Cat and An Ox. Red Cat stands for reduction is at the cathode. An Ox stands for anode is oxidation.
