Electrolysis of CuSO4 (aq) was carried out using Cu - electrode and a steady current. Which graph shows the change in mass of the cathode with time?
Correct answer: A. A
- A. A
- B. B
- C. C
- D. D
Explanation
The graph shown by Option A represents a linear increase in mass over time, which is correct. During the electrolysis of Cu2SO4 with a copper electrode, copper ions are reduced and deposited on the cathode, causing a steady increase in mass.

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.
