how is nitric acid prepared in the laboratory.what are its properties and uses
Answers
Answer:
In general, the process for nitric acid manufacture consists of preheating the air, mixing it with ammonia gas, passing it over a platinum catalyst, extracting the heat produced from this reaction by using it to preheat the incoming air and then cooling further, adding secondary air and then absorb- ing .Nitric acid is used in the production of ammonium nitrate for fertilizers, making plastics, and in the manufacture of dyes. It is also used for making explosives such as nitroglycerin and TNT.Nitric acid, (HNO3), colourless, fuming, and highly corrosive liquid (freezing point −42 °C [−44 °F], boiling point 83 °C [181 °F]) that is a common laboratory reagent and an important industrial chemical for the manufacture of fertilizers and explosives. It is toxic and can cause severe burns.
