Which chemical compound is used in car batteries and has the formula PbSO4?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Lead sulfate.
The chemical compound used in car batteries with the formula PbSO₄ is Lead sulfate. Lead sulfate forms as a result of the chemical reactions that take place in the battery during discharge and recharge cycles. In a lead-acid battery, the positive and negative plates are made of lead dioxide (PbO₂) and lead (Pb), respectively, and when the battery discharges, lead sulfate (PbSO₄) forms on both plates. The process is reversed during recharging.
