Barium Carbonate Precipitation

BaCl₂ + Na₂CO₃ → BaCO₃↓ + 2NaCl

نظرة عامة

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.

مثال من الحياة اليومية

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

الأهمية الصناعية

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