Barium iodide Chemical Properties,Usage,Production

  • Chemical Properties Colorless crystals, decomposes and reddens on exposure to air.Soluble in water; slightly soluble in alcohol.
  • Physical properties Barium iodide occurs in two forms, one anhydrous and the other as a dihydrate. Both are white solids. This salt is stable, but air and light sensitive. It is also hygroscopic and moisture sensitive. Barium iodide is incompatible with strong oxidizing agents.
  • Uses Preparation of other iodides.
  • Preparation Barium iodide is made by the neutralization of barium carbonate with HI in water:
    BaCO3＋2HI (aq)→BaI2 (aq)
    It is also made by the reaction of BaH2 with ammonium iodide in pyridine:
    BaH2＋2NH4I (aq)→BaI2 (aq)＋ 2NH3 (gas)＋H2 (gas)
    The product crystallizes as the hydrate BaI2·2H2O. If this heated, dehydration to anhydrous BaI2 occurs. The dihydrate dehydrates at 539°C to form BaI2.
