==Overview==
{{LabelImage
'''Potassium bicarbonate''' (also known as '''potassium hydrogen carbonate''' or '''potassium acid carbonate'''), is a colorless, odorless, slightly [[Base (chemistry)|basic]], salty substance. The compound is used as a source of [[carbon dioxide]] for leavening in baking, extinguishing fire in powder fire extinguishers, acting as a [[reagent]], and a strong [[buffering agent]] in medications. The US [[Food and Drug Administration]] (FDA) recognizes potassium bicarbonate as "[[generally recognized as safe]]". It is used as a base in foods to regulate pH.

Potassium bicarbonate is [[soluble]] in [[water]], and is often found added to bottled water to affect [[taste]]; however, it is not soluble in [[alcohol]]. Decomposition of the substance occurs between 100°[[Celsius|C]] and 120°C into [[Potassium|K]]<sub>2</sub>[[Carbon|C]][[Oxygen|O]]<sub>3</sub> ([[potassium carbonate]]), [[Hydrogen|H]]<sub>2</sub>[[Oxygen|O]] ([[water]]), and [[Carbon|C]][[Oxygen|O]]<sub>2</sub> ([[carbon dioxide]]). In [[concentration]]s greater than 0.5%, KHCO<sub>3</sub> can have phytotoxic effects on plants (potassium bicarbonate has widespread use in crops, especially for neutralizing [[acid]]ic soil), although there is no evidence of human [[carcinogenicity]], no adverse effects of overexposure, and no [[LD50|LD<sub>50</sub>]].
Physically, potassium bicarbonate occurs as a crystal or a soft white granular powder. It has a [[CAS registry number|CAS No]] [298-14-6]. It is manufactured by reacting [[potassium carbonate]] with [[carbon dioxide]] and [[water]]:
Potassium bicarbonate is used as a fire suppression agent ("BC powder") in some dry powder fire extinguishers, as the principal component of the Purple-K powder. It is the only dry chemical fire suppression agent recognized by the [[National Fire Protection Association]] for firefighting at airport crash rescue sites. It is about twice as effective in fire suppression as [[sodium bicarbonate]]. [http://www.nrl.navy.mil/content.php?P=PURPLEK]
