In which of the following reaction(s) H2SO4 act as an oxidising agent and as well as acid?
Correct answer: C. Cu+H2SO4 ⟶ CuSO4+SO2+ 2H2O
- A. C12H22O11 -------> 12C+11H2O
- B. S+H2SO4 ⟶ 3SO2 + 2H2O
- C. Cu+H2SO4 ⟶ CuSO4+SO2+ 2H2O
- D. All of the above
Explanation
In this reaction, H₂SO₄ is acting as an oxidizing agent because it causes copper (Cu) to lose electrons and be oxidized from Cu to Cu²+.H₂SO₄ is also acting as an acid because it donates H⁺ ions to the reaction.

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.
