In Lead-Acid battery, product formed at anode during discharging is:
Correct answer: A. PbSO₄
- A. PbSO₄
- B. Pb
- C. SO₂
- D. SO₄
Explanation
In a lead-acid battery, during discharge, the anode (positive electrode) undergoes oxidation. Lead (Pb) reacts with sulfuric acid (H₂SO₄) to form lead sulfate (PbSO₄) and release electrons. The reaction at the anode is:Pb(s) + SO₄²⁻(aq) → PbSO₄(s) + 2e⁻

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.
