CH3COOK

CH3COOK is the chemical formula for potassium acetate, also known as potassium ethanoate. It is an ionic salt formed from potassium cations (K+) and acetate anions (CH3COO−). As the conjugate base salt of acetic acid, it serves as a source of potassium in chemical and biological contexts.

Production and composition: Potassium acetate is typically prepared by neutralizing acetic acid with potassium hydroxide: CH3COOH + KOH → CH3COOK + H2O. It can also be produced by reacting acetic acid with potassium carbonate. The resulting solid consists of the acetate anion paired with potassium ions.

Properties: In solid form, potassium acetate appears as a white crystalline material. It is highly soluble in water and forms an aqueous solution that is mildly basic due to hydrolysis of the acetate ion (CH3COO− + H2O ⇌ CH3COOH + OH−).

Applications: In industry and laboratories, potassium acetate is used as a buffering agent and acidity regulator in food processing and various biochemical applications. It is also employed as a road de-icer and anti-icer, valued for being less corrosive than many chloride-based salts.

Safety considerations: Potassium acetate has relatively low toxicity but can irritate skin and eyes. Inhalation of dust should be avoided. Appropriate protective equipment should be used when handling the solid, and standard disposal procedures observed.
