Potassium citrate    The applications of potassium citrate (or tripotassium citrate) mainly derive from its alkaline properties. It is used to treat kidney stones composed of uric acid and cysteine, as well as other renal failures caused by excess acidity, including in veterinary applications. As an additive to soft drinks and other edibles, it also functions as an acid buffer, less bitter than other potassium salts, and with less sodium than trisodium citrate.
An additional use of potassium citrate is to supplement potassium in patients with hypokalemia, preventing and treating gout and arrhythmia.
