Ammonium Bicarbonate is an inorganic compound with formula (NH)4HCO3 which can be simplified to NH5CO3. It is a colorless solid that degrades into carbon dioxide, water, and ammonia. To produce this compound carbon dioxide is combined with ammonia:
CO2 + NH3 + H2O --> (NH)4HCO3
Ammonium bicarbonate can be used as a raising agent for baked goods, fertilizer for plants, producing fire-extinguishing compounds, pharmaceuticals, dyes, pigments, and for buffering solutions to slightly alkaline pH during chemical purification. Ammonium bicarbonate has also been used in a study that demonstrated that it can also produce sufficient voltage for hydrogen gas generation in a microbial reverse-electrodialysis electrolysis cell. It has also been used in a study that developed a fast and sensitive method for the simultaneous determination of Sudan dyes in food samples using partial filling micellar electrokinetic chromatography-mass spectrometry.
