Question

Which of the following statements is true for electrolytic cell?

• A. Oxidation occurs at positive electrode
• B. Oxidation occurs at negative electrode
• C. Anode is negative and cathode is positive electrode
• D. Reduction occurs at positive electrode

Hint:

Remember: Oxidation always occurs at the anode, regardless of whether the cell is galvanic or electrolytic.

Answer 1

The Correct Option is A

Step 1: Nature of electrolytic cell.
In an electrolytic cell, electrical energy is used to drive a non-spontaneous chemical reaction. The polarity of electrodes is determined by the external power supply.

Step 2: Oxidation and reduction.
Oxidation always occurs at the anode, and reduction always occurs at the cathode. In an electrolytic cell, the anode is connected to the positive terminal of the battery.

Step 3: Analysis of options.
Since oxidation occurs at the anode and the anode is positive in an electrolytic cell, oxidation occurs at the positive electrode.

Step 4: Conclusion.
Therefore, the correct statement is (A) Oxidation occurs at positive electrode.
