- D. Ionic compounds are formed
Answer
Positive ions gain electrons
Explanation
At the cathode, reduction occurs, meaning positive ions gain electrons.
Common mistake
Confusing Cathode and Anode Half Equations
Students often confuse the half equations for the cathode and anode during electrolysis, mistakenly attributing the reduction process to the anode instead of the cathode.
Remember that reduction occurs at the cathode where positive ions gain electrons, while oxidation occurs at the anode where negative ions lose electrons. Practice identifying the charge of ions to help distinguish between the two.
