Barium Acetate, Formula, Chemical Properties, Preparation, Uses

Barium Acetate

Barium acetate is a chemical compound that has consists of salt of barium and acetic acid. It is highly soluble in water and used as a cationization agent. It decomposed the carbonate when its heating at the room temperature.  The systematic IUPAC name is known as Barium acetate. The chemical or molecular formula of Barium acetate is C4H6BaO4.

Structural Formula

This is the structural formula of the Barium acetate:

Barium Acetate

Chemical Formula

The chemical formula or molecular formula of Barium acetate is C4H6BaO4.

Preparation Method

When the barium carbonate is reacted with the acetic acid it forms the barium acetate and the carbon dioxide and water as the byproduct. Further it is heated above 41C. at that time the barium sulfide can be used to reacting with the acetic acid to form the barium acetate and hydrogen sulfide as the byproduct. This solvent is evaporated off and the barium acetate crystallized.
