Potassium Acetate is also known as potassium ethanoate, is the potassium salt of acetic acid with the chemical formula CH₃COOK (C₂H₃KO₂). It is a hygroscopic solid at room temperature and is highly soluble in water. The potassium acetate structure is ionic, with the negative charge of the acetate ion distributed across its two oxygen atoms. Because of its high solubility and buffering capacity, it has useful physicochemical properties in aqueous systems. It is commonly used as a buffering and neutralizing agent and as a base in organic synthesis.
CAS No.: 127-08-2
Synonyms: Potassium ethanoate, acetic acid potassium salt, and diuretic salt.

Potassium Acetate is used as a buffering and neutralizing agent, a base and catalyst in organic synthesis and a source of potassium ions. It also has applications in pharmaceutical formulations, food processing, laboratory research, polymer chemistry and de-icing systems.
Potassium acetate (CH₃COOK) is also known as potassium ethanoate or ethanoic acid potassium salt. It is the potassium salt of acetic acid (CH₃COOH), commonly used in electrolyte formulations, acetate buffer systems, chemical synthesis, and as a de-icing agent.
Potassium Acetate and potassium Chloride both contain potassium as an elemental component. Potassium chloride (KCl) is the potassium salt of hydrochloric acid, whereas potassium acetate (CH₃COOK) is the potassium salt of acetic acid. Both are used as potassium sources in the food and textile Industry, pharmaceutical formulation and laboratory applications.
Potassium acetate is highly soluble in water. It readily dissociates into potassium (K⁺) and acetate (CH₃COO⁻) ions, making it suitable for preparing aqueous solutions and buffers.
