Barium formate is the barium salt of formic acid with the constitutional formula Ba (HCOO) ₂ .

Manufacturing

Barium formate can be prepared by reaction of barium hydroxide will be illustrated with formic acid.

${\displaystyle \mathrm {Ba(OH)_{2}+2\ HCOOH\ \longrightarrow \ Ba(HCOO)_{2}+2\ H_{2}O} }$

properties

Temperature dependence of the solubility of anhydrous barium formate in water

Barium formate crystallizes as a dihydrate in the orthorhombic crystal system . The crystals are isomorphic to calcium formate and strontium formate . The anhydrate crystallizes in the monoclinic crystal system .
