Potassium Acetate, Formula, Preparation Method, Chemical Properties

Potassium Acetate

Potassium acetate has an equal number of acetate and potassium ions present. It is derived from the potassium salt of acetic acid. In earlier it is used as a expectorants and diuretics. It has associated with the various functions such as physiological and maintaining normal renal function and blood pressure. It has consists of one acetate anion and one potassium cation. These two ions are bonded by the ionic bonds. The systematic IUPAC name is known as potassium acetate. The chemical or molecular formula of potassium acetate is CH3CO2K . It is also known as the potassium ethanoate.

Structural Formula

This is the structural formula of the potassium acetate:

Potassium Acetate

Chemical Formula

The chemical formula of the potassium acetate is CH3CO2K.

Preparation Method

When the potassium hydroxide is reacted with the acetate and it is formed the potassium acetate by the neutralization process. The reaction is as follows.

CH3COOH + KOH → CH3COOK + H2O

By crystallization and evaporation process a small volume of water is added to the potassium carbonate in the acetic solution. It is evolved the hydrogen and oxygen gas.

K2CO3 + 2CH3COOH → 2CH3COOK + H2O + CO2
