Question

State the chemical equation for the reaction that occurs when a lead-acid battery is
being re-charged or discharged

Answer 1

Answer:

Lead and lead dioxide, the active materials on the battery's plates, react with sulfuric acid in the electrolyte to form lead sulfate. The lead sulfate first forms in a finely divided, amorphous state and easily reverts to lead, lead dioxide, and sulfuric acid when the battery recharges.

Explanation:

example anode reaction: Pb(s) + SO42-(aq) →

cathode reaction: PbO2(s) + 4H+(aq) + SO42-(aq) + 2e - →

overall reaction: Pb(s) + PbO2(s) + 4H+(aq) + 2SO42-(aq) →
