Element percentages for the elements in barium dichloride
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
