13718-00-8 Usage
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.
Check Digit Verification of cas no
The CAS Registry Mumber 13718-00-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,1 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13718-00:
(7*1)+(6*3)+(5*7)+(4*1)+(3*8)+(2*0)+(1*0)=88
88 % 10 = 8
So 13718-00-8 is a valid CAS Registry Number.
