What is the primary reaction occurring in a lead-acid battery during discharge?
Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H2O
PbSO4 + 2H2O → Pb + PbO2 + 2H2SO4
2Pb + 2H2SO4 → 2PbSO4 + H2
PbO2 + 2H2SO4 → Pb + 2H2O + O2
Show Solution

Q
Q: What is the primary reaction occurring in a lead-acid battery during discharge?
Solution:
During discharge, the primary reaction in a lead-acid battery is Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H2O.
Steps: 6
Show Steps
Step 1: Understand that a lead-acid battery has two main components: lead (Pb) and lead dioxide (PbO2).
Step 2: Know that during discharge, the battery releases energy to power devices.
Step 3: Recognize that sulfuric acid (H2SO4) is also involved in the reaction.
Step 4: The reaction starts with lead (Pb) and lead dioxide (PbO2) combining with sulfuric acid (H2SO4).
Step 5: This combination produces lead sulfate (PbSO4) and water (H2O).
Step 6: The overall chemical reaction can be written as: Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H2O.
