Barium Sulfate Precipitation

BaCl₂ + Na₂SO₄ → BaSO₄↓ + 2NaCl

Обзор

Barium chloride reacts with sodium sulfate to form an extremely insoluble white precipitate of barium sulfate (Ksp = 1.1 × 10⁻¹⁰). BaSO₄ is so insoluble that it is safe to ingest for medical imaging despite barium's toxicity. The precipitate forms instantly as a dense, finely divided white solid.
