During electrolysis of CuSO₄(aq) using copper electrodes, the cathode:
Correct answer: A. Increases in mass
- A. Increases in mass
- B. Decreases in mass
- C. Remains unchanged
- D. Dissolves completely
Explanation
Cu²⁺ + 2e⁻ → Cu ( deposited ) so mass of the cathode increases.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
