Element	%
Ba	65.95
Cl	34.05

Synthesis

Barium chloride is made by the neutralization of barium hydroxide with HCl in water. The product crystallizes as the hydrate BaCl₂.2H₂O [10326-27-9]. If this heated, dehydration to anhydrous BaCl₂ occurs.

Ba(OH)₂ + 2HCl(aq) → BaCl₂(aq) + 2H₂O

Solid state structure

• Geometry of barium: 4 coordinate: tetrahedral
• Prototypical structure: CaF2 (fluorite)
