Potassium Acetate

Skeletal structure of potassium acetate

Potassium acetate is a chemical compound with the formula KCH_CO_. It is the potassium salt of acetic acid and appears as a white, crystalline solid. Potassium acetate is used in various applications, including as a food additive, a de-icing agent, and in the medical field.

Chemical Properties

Potassium acetate is a salt that is highly soluble in water. It has a molar mass of 98.15 g/mol and a melting point of 292 °C. In aqueous solution, it dissociates into potassium ions (K_) and acetate ions (CH_COO_).

Uses

Food Industry

In the food industry, potassium acetate is used as a food additive and preservative. It is designated as E261 and is used to regulate acidity and as a buffering agent.

De-icing Agent

Potassium acetate is commonly used as a de-icing agent for airport runways and roads. It is preferred over other salts because it is less corrosive to metals and less harmful to the environment.

Medical Applications

In medicine, potassium acetate is used as an electrolyte replenisher. It is administered intravenously to treat or prevent potassium deficiency in patients.

Safety and Handling

Potassium acetate is generally regarded as safe when handled properly. However, it should be stored in a cool, dry place and kept away from moisture. In case of contact with skin or eyes, it should be rinsed thoroughly with water.
