Detailed Solution
Download Solution PDFThe correct answer is Lead sulfate
Key Points
- Lead sulfate (PbSO4) is the chemical compound used in car batteries.
- During the discharge of a lead-acid battery, lead dioxide (PbO2) and sponge lead (Pb) react with sulfuric acid (H2SO4) to form lead sulfate (PbSO4) and water (H2O).
- This reaction is reversible, allowing the battery to be recharged.
- Lead sulfate is a white crystalline solid that forms on the plates of the battery during discharge.
Additional Information
- Lead-acid batteries are commonly used in vehicles because they are cost-effective and can supply high surge currents.
- The chemical reaction inside a lead-acid battery is essential for converting chemical energy into electrical energy.
- Proper maintenance of the battery ensures longevity and efficient performance.
- Lead-acid batteries are also used in backup power supplies and energy storage systems.
