Ammonium Bicarbonate Basic Info: Other names:Acid ammonium carbonate Ammonium hydrogen carbonate Ammonium bicarbonate Ammonium acid carbonate Chemical Formula:NH4HCO3 Molar Mass:79 06 g mol CAS 1066-33-7 PubChem 14013 EINECS 213-977-5 RTECS BO8600000 Properties Chemical Formula:NH4HCO3 Appearance:White orthorhombic or monoclinic crystal Odor:Pungent Odor Density(g/cm):1.58g/cm PH Value:7.0-8.5 Melting Point:105 Solubility:22g/100gWater(20) Flash Point:169.8 Boiling Point: Other Info Applications: It is commonly used as an inexpensive nitrogen fertilizer in China, but is now being phased out in favor of urea for quality and stability. This compound is used as a component in the production of fire-extinguishing compounds, pharmaceuticals, dyes, pigments, and it is also a basic fertilizer being a source of ammonia. Ammonium bicarbonate is still widely used in the plastic and rubber industry, in the manufacture of ceramics, in chrome leather tanning, and for the synthesis of catalysts.[citation needed] It is also used for buffering solutions to slightly alkaline pH during chemical purification, such as high-performance liquid chromatography. Because it entirely decomposes to volatile compounds this allows rapid recovery of the compound of interest by freeze-drying. Ammonium bicarbonate is also a key component of the expectorant cough syrup "Senega and Ammonia".
