Barium Carbonate Precipitation

BaCl₂ + Na₂CO₃ → BaCO₃↓ + 2NaCl

Visão geral

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.

Exemplo do cotidiano

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

Importância industrial

O BaCO₃ é utilizado no fabrico de tijolos e ladrilhos para prevenir a eflorescência, em vidrados cerâmicos e como precursor de outros compostos de bário.
