Zinc Sulfide Precipitation

ZnSO₄ + Na₂S → ZnS↓ + Na₂SO₄

نظرة عامة

Zinc sulfate reacts with sodium sulfide to form a white precipitate of zinc sulfide (Ksp = 2 × 10⁻²⁵). ZnS occurs naturally as the mineral sphalerite, the most important zinc ore. Zinc sulfide phosphors are used in cathode ray tubes and luminous paints.
