Ammonium bicarbonate
Ammonium bicarbonate consists of white crystalline solids that are hygroscopic, meaning they readily absorb moisture and may cake. The material has a characteristic pungent odor of ammonia and decomposes when heated. It is commonly employed as a leavening and foaming agent and must be stored in a sealed container in a cool location.

In the pharmaceutical field, it was once used in the preparation of expectorant medications. By utilizing the ammonia gas generated from its decomposition, it gently irritates the respiratory tract, facilitating the expulsion of phlegm. Its mild alkalinity and decomposition properties make it commonly used in the preparation of certain analytical reagents and buffer solutions, establishing it as a fundamental and versatile chemical raw material in laboratories.
