Chemical compound

Barium acetate ([Barium|Ba]2) is the salt of barium(II) and acetic acid. It is used in chemistry and manufacturing as a soluble source of barium and is toxic to humans.

Preparation

[edit]

Barium acetate is generally produced by the reaction of acetic acid with barium carbonate:[4]

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

The reaction is performed in solution and the barium acetate crystalizes out at temperatures above 41 °C. Between 25 and 40 °C, the monohydrate version crystalizes. Alternatively, barium sulfide can be used:[4]

BaS + 2 CH3COOH → (CH3COO)2Ba + H2S

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

Properties

[edit]

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.

Reactions

[edit]

Barium acetate can be used in metathesis reactions.

When heated in air, barium acetate decomposes to the carbonate.[citation needed]

Uses

[edit]

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]

[edit]

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). That episode and other crime documentaries about the Robards do not name the chemical.

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 an episode of Deadly Women.[citation needed]
