Barium acetate (Ba(C₂H₃O₂)₂) is the salt of barium(II) and acetic acid. Barium acetate is toxic to humans, but has use in chemistry and manufacturing.

Preparation[]

Barium acetate is generally produced by the reaction of acetic acid with barium carbonate:^[2]

BaCO₃ + 2 CH₃COOH → (CH₃COO)₂Ba + CO₂ + H₂O

The reaction is performed in solution and the barium acetate crystallizes out. Alternatively, barium sulfide can be used:^[2]

BaS + 2 CH₃COOH → (CH₃COO)₂Ba + H₂S

Again, the solvent is evaporated off and the barium acetate crystallized.

Properties[]

Barium acetate is a white powder, which is highly soluble: at 0 °C, 55.8 g of barium acetate can be dissolved in 100 g of water. It decomposes upon heating into barium carbonate.^{[citation needed]}

Reactions[]

When heated in air, barium acetate decomposes to the carbonate. It reacts with acids: reaction with sulfuric acid, hydrochloric acid and nitric acid give the sulfate, chloride and nitrate respectively.^{[citation needed]}

Uses[]

Barium acetate is used as a mordant for printing textile fabrics, for drying paints and varnishes and in lubricating oil. In chemistry, it is used in the preparation of other acetates; and as a catalyst in organic synthesis.^{[citation needed]}

In Pop Culture[]

Barium Acetate was featured in a 2001 episode of the television series Forensic Files, recounting the 1993 murder of a man by his teenaged daughter (Marie Robards), though the episode and other crime documentary shows examining the Robards case excluded the mention of barium acetate.

Barium Acetate was featured in a 2014 episode of the crime documentary series Redrum.

Barium acetate was named as the choice poison of a teen's murder of her father in Deadly Women "Parents Peril", S6 E2.^{[citation needed]}
