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

Correct option is D

The correct answer is (d) Lead sulfate.
· Lead sulfate (PbSO4) is the chemical compound that forms on the plates of a lead-acid car battery during the discharge process.
· In a lead-acid battery, sulfuric acid reacts with lead dioxide (PbO2) on the positive plate and lead (Pb) on the negative plate to form lead sulfate (PbSO4) on both plates during discharge.
· When the battery is charged, the lead sulfate is converted back to lead and lead dioxide, allowing the battery to be recharged.
Information Booster:
Sulfuric acid (H2SO4):
· Sulfuric acid is the electrolyte used in lead-acid batteries, facilitating the chemical reactions inside the battery.
Lead sulphide (PbS):
· Lead sulfide is a naturally occurring mineral called galena, but it is not used in car batteries.
Lead oxide (PbO):
· Lead oxide is used in the positive plates of lead-acid batteries, but it is not the primary compound that forms during discharge.
