Barium Carbonate Precipitation

BaCl2 + Na2CO3 → BaCO3↓ + 2NaCl

概要

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.

日常の例

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

産業上の重要性

BaCO₃は白華(エフロレッセンス)を防ぐためのレンガやタイル製造、セラミック釉薬、そして他のバリウム化合物の前駆体として使用されています。
