Ammonium carbonate - Wikipedia

Ammonium carbonate is a salt with the chemical formula (NH 4) 2 CO 3.Since it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt.It is also known as baker's ammonia and was a predecessor to the more modern leavening agents baking soda and baking powder.It is a component of what was formerly known as sal volatile and ...
