Question

Which of the following statements are true regarding electrolytic cell ?

• A. Positive electrode is called cathode and negative electrode is called anode
• B. Oxidation takes place at anode and reduction takes place at cathode
• C. Spontaneous redox reaction takes place in electrolytic cell
• D. Current flows from anode to cathode in the inside of the cell

Answer 1

Answer: (B)

Oxidation takes place at anode and reduction takes place at cathode

In an electrolytic cell, there is conversion of electrical energy into chemical energy. The loss of electrons or oxidation takes place at anode while gain of electrons or reduction takes place at cathode.
