What happens at the cathode in an electrolytic cell?A.ReductionB.MeltingC.OxidationD.Turning an ion into an uncharged atom

Step 1: Identify the Electrolytic Cell Process

In an electrolytic cell, an external voltage is applied to drive a non-spontaneous reaction. Thus, the electrochemical reactions occur at the electrodes.

Step 2: Understanding Cathode Behavior

At the cathode in any electrochemical cell (including electrolytic cells), reduction occurs. This means that ions gain electrons and are converted into neutral atoms.

Step 3: Define the Answer Options

1. A. Reduction - This is the process where an ion gains electrons.
2. B. Melting - This is a phase change and does not involve electron transfer.
3. C. Oxidation - This is the process where an atom or ion loses electrons.
4. D. Turning an ion into an uncharged atom - This is indeed what happens during reduction.

Step 4: Conclusion

In an electrolytic cell, the cathode is where reduction takes place, as ions gain electrons and are reduced to uncharged atoms.

Final Answer

A. Reduction
