Cu + HNO3 → Cu (NO3)2 + NO + H2O. Copper + nitric acid ---> copper(II) nitrate + nitrogen dioxide + water. Metallic copper reacts with nitric acid to produce copper nitrate, nitric oxide and water in aqueous solution. Alan F Rawle. Calculate the percent yield of this process if 1.235 g of copper produced 1.452 g of copper . Close. Chemically, nitric acid is made by bubbling nitrogen dioxide into water. 2.Oxidation of NO to NO 2: Nitric oxide is cooled to about 50 0 C to 100 0 C and air oxidized to nitrogen dioxide. The nitrate ion can easily be identified by heating copper turnings along with concentrated sulfuric acid. Equation for copper nitrateWhat are the names of the oxide and acid you use to create copper nitrate? urea-ammonium nitrate solutions (UAN) and some kinds of complex NP and NPK fertilizers (nitro-phosphates).The weak nitric acid production is based on three main chemical processes: catalytic oxidation of ammonia in air to nitric oxide, homogeneous oxidation of NO to NO 2 and absorption of NO 2 in water. Copper reacts with nitric acid, forming blue Cu2+ ions. The equations are as follows: 2 Cu(NO 3) 2 → 2 CuO + 4 NO 2 + O 2 3NO 2 + H 2 O → 2HNO 3 + NO. Principle: 1.Catalytic oxidation of NH 3 to NO : When ammonia is oxidized with oxygen in presence of catalyst platinum and rhodium in 9 : 1 ratio at about 800 0 C and 5 atmospheric pressure, nitric oxide is formed.
