This molecule is available in the trigonal pyramidal shape where one nitrogen is attached with three hydrogen atoms. Further, the nitrogen atom had a lone electron pair that successful makes the ammonia as a base. NH3 is a polar molecule that quickly forms hydrogen bonds and making it high miscible with water.
The presence of NH3 can be felt strongly in the human body and secreted to kidneys to neutralize the excess acid effects. It is available in small quantity inside rainwater, volcanic areas, or atmosphere etc. The compound is prepared commercially by Haber-Bosch process and hydrogen atoms and nitrogen atoms will connect together in the presence of a metal catalyst to release the ammonia gas at high temperature or pressure conditions.
N2 + 3H2 → 2NH3
Further, the ammonia is a colorless agent with a sharp and penetrating odor with a melting point of -33.35 degree Celsius. The freezing point of the compound is -77.7 ° where NH3 gas can be liquified quickly. Let us switch to the chemical properties now, where ammonia is always the weak base and combines with a variety of acids to form ammonium salts in the end.
When ammonia and water combine together, it will result in an exothermic reaction and forming aqueous solution too that is named as the ammonium hydroxide (NH4OH). The major uses of ammonia involve fertilizers, polymers, cleaning agents, or refrigerants etc. The chemical compound has a pungent smell and it can seriously irritate the nose, eyes, or skin etc when inhaled in large quantities.
