Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH 3. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers.mmonia is miscible with water. In an aqueous solution, it can be expelled by boiling. The aqueous solution of ammonia is basic. The maximum concentration of ammonia in water (a saturated solution) has a density of 0.880 g/cm 3 and is often known as '.880 ammonia'.
NaHCO 3 is mainly prepared by the Solvay process, which is the reaction of sodium chloride, ammonia, and carbon dioxide in water. Calcium carbonate is used as the source of CO 2 and the resultant calcium oxide is used to recover the ammonia from the ammonium chloride.The product shows a low purity (75%).aHCO 3 is mainly prepared by the Solvay process, which is the reaction of sodium chloride, ammonia, and carbon dioxide in water.
