Barium iodide

Barium iodide Chemische Eigenschaften,Einsatz,Produktion Methoden

• Chemische Eigenschaften

  Colorless crystals, decomposes and reddens on exposure to air.Soluble in water; slightly soluble in alcohol.

• Physikalische Eigenschaften

  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.

• Verwenden

  Preparation of other iodides.

• synthetische

  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.
