Potassium bicarbonate (IUPAC name: potassium hydrogencarbonate, also known as potassium acid carbonate) is the inorganic compound with the chemical formula KHCO3. It is a white solid.[1]
As an inexpensive, nontoxic base, it is widely used in diverse application to regulate pH or as a reagent. Examples include as buffering agent in medications, an additive in winemaking.
Potassium bicarbonate is often added to bottled water to improve taste,[7] and is also used in club soda.
Medical uses and health
Higher potassium intake may prevent development of kidney stone disease.[8] Higher potassium intake is associated with a reduced risk of stroke.[9]
Potassium bicarbonate is a contact killer for Spanish moss when mixed 1⁄4 cup per gallon.[16]
History
The word saleratus, from Latinsal æratus meaning "aerated salt", first used in the nineteenth century, refers to both potassium bicarbonate and sodium bicarbonate.[17]
