	'''Potassium citrate''' (also known as '''tripotassium citrate''') is a [[potassium]] [[salt (chemistry)\|salt]] of [[citric acid]] with the molecular formula K<sub>3</sub>C<sub>6</sub>H<sub>5</sub>O<sub>7</sub>. It is a white, [[hygroscopic]] crystalline powder. It is odorless with a [[salt\|saline]] taste. It contains 38.28% potassium by mass. In the monohydrate form, it is highly [[hygroscopic]] and [[deliquescent]].
