On the electrolysis of H2SO4 (dil) solution by using inert electrode, which of the following is deposited or released at anode electrode?
Correct answer: B. O2 gas is released
- A. H2gas is released
- B. O2 gas is released
- C. SO2 gas is released
- D. Neither O2 or SO2 gas is released
Explanation
On the electrolysis of dilute H2SO4 solution by using inert electrodes, oxygen gas is released at the anode electrode.The reason for this is that the standard electrode potential of oxygen is more positive than the standard electrode potential of sulfur. Therefore, the sulfate ions in the solution will be oxidized at the anode, while the hydrogen ions will not.

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.
