Technical Document
Brief Overview
Potassium acetate is also called diuretic salt or potassium ethanoate, or acetic acid potassium salt. It is an essential macro-mineral and a potassium salt which consists of an equal numbers of acetate and potassium ions. It is a deliquescent white crystalline powder, soluble in water, and has a pH value between 7.5 - 9.0. It is widely used to replenish electrolytes, and as well as a urinary and systemic alkaliser. Earlier it was used in expectorants and diuretics.
Manufacturing Process
Potassium acetate is prepared by reacting a potassium-containing base such as potassium hydroxide or potassium carbonate with acetic acid in the following reaction:
CH3COOH + KOH → CH3CO2K + H2O
This is also known as an acid-base neutralization reaction. Potassium acetate is the salt that forms along with water as acetic acid and potassium hydroxide are neutralized together.
