Strontium Sulfate Precipitation
SrCl2 + Na2SO4 → SrSO4↓ + 2NaCl
نظرة عامة
Strontium chloride reacts with sodium sulfate to form a white precipitate of strontium sulfate (Ksp = 3.4 × 10⁻⁷). SrSO₄ is moderately insoluble, less so than BaSO₄ but more than CaSO₄. The mineral form is celestine, the primary source of strontium.
