Barium Sulfate Precipitation

BaCl2 + Na2SO4 → BaSO4↓ + 2NaCl

अवलोकन

Barium chloride reacts with sodium sulfate to form an extremely insoluble white precipitate of barium sulfate (Ksp = 1.1 × 10⁻¹⁰). BaSO₄ is so insoluble that it is safe to ingest for medical imaging despite barium's toxicity. The precipitate forms instantly as a dense, finely divided white solid.

रोजमर्रा का उदाहरण

Barium sulfate is the white liquid (barium meal) patients drink before gastrointestinal X-rays to make the digestive tract visible.

औद्योगिक महत्व

BaSO₄ is used as a radiocontrast agent, as a white pigment (blanc fixe) in paints, in oil well drilling mud, and as a filler in plastics and paper.
