Answer
Cathode
Explanation
Reduction occurs at the cathode because positive ions gain electrons at this electrode.
Common mistake
Common Mistake in Writing Half Equations
Students often confuse the direction of electron flow and incorrectly write half equations for the cathode, sometimes placing electrons on the wrong side.
Remember that reduction occurs at the cathode, meaning positive ions gain electrons. Always place electrons on the left side of the equation when writing half equations for the cathode.
