Physical and Chemical Properties:Nitric Acid (HNO3) is a clear, colorless to slightly yellow inorganic acid. It is a strong monobasic acid and a powerful oxidizing agent.Nitric acid is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercial available nitric acid has a concentration of 68% in water.&©|160;

Nitric acid (HNO3) is an extremely important chemical used in the manufacture of fertilisers and explosives. It is made from ammonia by the Ostwald Process (developed in 1902 by the German chemist Wilhelm Ostwald, who got the Nobel prize in 1909). This process reacts together O2 and NH3 at 850℃ and 5 atmospheres pressure, with the help of Platinum and Rhodium catalysts, to make NO. This is then oxidised to NO2, which is then dissolved in water to make HNO3. The Ostwald process was discovered just in time fo |
