Ammonium chloride ( ) is an inorganic compound best known as a white crystalline salt. Traditionally called , it is naturally occurring in volcanic regions and is a critical industrial byproduct of the Solvay process used to produce soda ash. The "Sixth Taste": A Biological Breakthrough induces

: Despite being a "warning" taste, it is a hallmark of Nordic salty licorice ( salmiakki ), where it provides a distinctive sharp, stinging sensation. Medical and Physiological Effects Medical and Physiological Effects : The kidney uses

: The kidney uses ammonium ions to maintain homeostasis; clinically, it is used as a systemic acidifying agent to treat metabolic alkalosis.

Recent scientific studies have proposed that ammonium chloride may represent a , joining sweet, sour, salty, bitter, and umami.
