Question

Which of the following statements are correct regarding electrolytic cells?

i) Electrolytic cell converts electrical energy to chemical energy.
ii) Anode is connected to the positive terminal of the battery.
iii) Cathode is connected to the negative terminal of the battery.
iv) Electrodes are dipped into a non-electrolyte solution.

• A. i only
• B. i and ii
• C. i , ii and iii
• D. ii and iv

Answer 1

The correct option is C i , ii and iii

$\bullet$ An electrolytic cell is a device that has two electrodes immersed in an electrolyte. It converts electrical energy into chemical energy.
$\bullet$ One of the electrodes of the cell is connected to the positive terminal of the battery and is called the anode.
$\bullet$ The other electrode is connected to the negative terminal of the battery and is called the cathode.

Hence, statement i, ii, and iii are correct.
