Ammonium potassium tartrate

Description:

Ammonium potassium tartrate, also known as potassium ammonium tartrate or Rochelle salt, is a chemical compound with the formula KNH4C4H4O6. It is a white, crystalline substance that is highly soluble in water, making it useful in various applications. This compound is a double salt formed from tartaric acid, and it contains both ammonium and potassium ions. It exhibits properties typical of salts, such as the ability to form a saturated solution at elevated temperatures. Ammonium potassium tartrate is often used in food and pharmaceutical industries, particularly as a stabilizing agent or in the preparation of certain formulations. Additionally, it has applications in analytical chemistry, where it can serve as a reagent. The compound is generally regarded as safe for consumption in moderate amounts, but like many salts, excessive intake can lead to health issues. Its hygroscopic nature allows it to absorb moisture from the air, which can affect its storage and handling.
