Ammonium Chemical

Sal ammoniac or Salammoniac, is a rare naturally occurring mineral composed of ammonium chloride, NH₄Cl. It forms colorless, white, or yellow-brown crystals in the isometric-hexoctahedral class.
Sal ammoniac has also been used in the past in bakery products to give cookies or biscuits their crisp texture, but the application of food grade baking ammonia (ammonium carbonate) is generally being substituted with the creation of modern baking powder or baking soda (sodium bicarbonate). Sal ammoniac is known, inter alia, by its use in salmiac liquorice, for instance salty liquorice or salmiak pastilles. In addition, the mineral or better its synthetic counterpart also serves for the production of cooling baths as well as in the dyeing and leather tanning.

Ammonium bicarbonate is an inorganic compound with formula HCO The compound has many names, reflecting its long history. Chemically speaking, it is the bicarbonate salt of the ammonium ion. It is a colourless solid that degrades readily to carbon dioxide, water and ammonia.
