Copper nitrate is insoluble in ethyl acetate. I put 3 CuO because there are 3 parts of CuO resulting from the first reaction and so, there are 3 parts of CuO reacting with the excess acid. Hydrated copper nitrate can be prepared by hydration of the anhydrous material or by treating copper metal with an aqueous solution of silver nitrate or concentrated nitric acid:. Copper reacts with nitric acid to produce copper nitrate, nitrogen dioxide gas, and water. Nitric acid is without action on gold, platinum, iridium and rhodium. When the copper is first oxidized, the solution is very concentrated, and the Cu 2+ product is initially coordinated to nitrate ions from the nitric acid, giving the solution first a green, and then a greenish-brownish color.

Nitrogen Dioxide Is Poisonous And Is A Primary Cause Of Smog. A horse trainer was banned for naming his horse "Grape Soda" ,apparently a racist epithet. A. Hantzsch (Berichte, 1925, 55, P. believes that con centrated nitric acid is chiefly composed of "nitronium" nitrate, [N(OH)3] (NO3)2. In this reaction, copper is oxidized while nitric acid is reduced to nitric oxide. There are actually two equations for the reaction of copper with nitric acid. When reaction will start slowly and copper will start coming on iron or steel piece then leave it for some hours. (See also ACIDS.) If it is concentrated and in excess then the ratio is 1:4 copper to nitric acid. In the reaction of the metal with diluted acid, copper nitrate and nitrogen divalent oxide form in the ratio of 75% and 25%. Copper reacts with nitric acid, forming blue Cu2+ ions.
