Lead Sulfate Precipitation

Pb(NO3)2 + Na2SO4 → PbSO4↓ + 2NaNO3

अवलोकन

Lead nitrate reacts with sodium sulfate to form a white precipitate of lead sulfate (Ksp = 2.5 × 10⁻⁸). PbSO₄ is the discharged form of lead-acid battery electrodes. The mineral form is anglesite, named after Anglesey in Wales.

रोजमर्रा का उदाहरण

When a car battery dies, both electrodes have converted to lead sulfate in a process called sulfation, which is reversed by charging.

औद्योगिक महत्व

Lead sulfate formation limits lead-acid battery capacity. Understanding and preventing sulfation is key to battery longevity.
