Barium Carbonate Precipitation

BaCl2 + Na2CO3 → BaCO3↓ + 2NaCl

अवलोकन

Barium chloride reacts with sodium carbonate to form a white precipitate of barium carbonate (Ksp = 2.6 × 10⁻⁹). BaCO₃ occurs naturally as the mineral witherite. It dissolves in dilute acids with effervescence, releasing CO₂.

रोजमर्रा का उदाहरण

Barium carbonate is used in rat poison because its acid-solubility allows it to dissolve in stomach acid, releasing toxic barium ions.

औद्योगिक महत्व

BaCO₃ is used in brick and tile manufacturing to prevent white scum (efflorescence), in ceramic glazes, and as a precursor for other barium compounds.
