Regents Chemistry Exam August 2025 Question 25
25 Where do oxidation and reduction occur in an electrochemical cell?
(1) Oxidation occurs at the anode and reduction occurs at the cathode.
(2) Oxidation occurs at the anode and reduction occurs in the salt bridge.
(3) Oxidation occurs at the cathode and reduction occurs at the anode.
(4) Oxidation occurs at the cathode and reduction occurs in the salt bridge.
Solution:
We can use a mnemonic to memorize this. Red Cat and An Ox.
Red Cat = reduction is at the cathode
An Ox= anode is oxidation Choice 1 is the correct answer.
