Potassium citrate

Potassium Citrate is a potassium salt of citric acid with the molecular formula K3C6H5O7. It is a white, crystalline powder or granules that is odorless with a saline taste. It is often used in food and pharmaceuticals as a buffering agent, chelating agent, stabilizer, or sequestrant.

Chemical Properties

Potassium Citrate is highly soluble in water and practically insoluble in ethanol. It has a melting point of 180°C and decomposes upon heating. It is non-combustible but enhances combustion of other substances.

Uses

Potassium Citrate is used in a wide range of applications. In the food industry, it is used as a food additive to regulate acidity and is known as E number E332. Medicinally, it is used to prevent certain types of kidney stones and gout. It is also used in the production of carbonated beverages, to impart a slightly tart flavor.

Health Effects

Potassium Citrate is generally safe for consumption. However, high doses can lead to hyperkalemia, a condition characterized by high levels of potassium in the blood. Symptoms of hyperkalemia include fatigue, weakness, numbness, and heart palpitations.
