Common mistake
Common Mistake in Writing Half Equations
Students often confuse the half equations for reactions at the anode and cathode, mistakenly writing the oxidation reaction at the cathode instead of the anode.
To fix this, remember that oxidation occurs at the anode, where negative ions lose electrons. Always identify the electrode and the type of reaction (oxidation or reduction) before writing the half equation.
