Which chemical compound is used in car batteries and has the formula PbSO₄? 

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.
