At which electrode does reduction always take place?
AAt the anode
BAt both of them
CAt neither one
DAt the cathode
Answer & Solution
Correct answer: D. At the cathode
1. Electrodes are named by the reaction that happens on them, not by their charge.
2. Reduction, the gain of electrons, always happens at the cathode.
3. Oxidation, the loss of electrons, always happens at the anode.
4. That naming holds for galvanic and for electrolytic cells alike.
