Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid with the molecular formula K3C6H5O7. It is a white, hygroscopic crystalline powder. It is odorless with a saline taste. It contains 38.28% potassium by mass. In the monohydrate form it is highly hygroscopic and deliquescent.
As a food additive, potassium citrate is used to regulate acidity. Medicinally, it may be used to control kidney stones derived from either uric acid or cystine.
1. Potassium citrate helps to reduce the acidity of the urine.
