In which of the following reaction(s) H2SO4 act as an oxidising agent and as well as acid?
Correct answer: C. C
- A. A
- B. B
- C. C
- D. D
Explanation
Cu + H2SO4 → CuO + H2O + SO2 (H2SO4 act as oxidant) CuO + H2SO4 → CuSO4 + H2O (H2SO4 act as acid)

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.
