Question
Explain why reduction occurs at the cathode during electrolysis.
Answer
Reduction occurs at the cathode because positive ions gain electrons. This process is essential for the formation of neutral atoms from their ionic forms.
Explanation
This question assesses the student's ability to explain the fundamental concept of reduction in electrolysis. It requires an understanding of the role of electrons and the nature of ions at the cathode.
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.
