Barium Carbonate Precipitation

BaCl₂ + Na₂CO₃ → BaCO₃↓ + 2NaCl

Descripción general

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.

Ejemplo cotidiano

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

Importancia industrial

El BaCO₃ se utiliza en la fabricación de ladrillos y azulejos para prevenir la eflorescencia blanca, en esmaltes cerámicos y como precursor de otros compuestos de bario.
