Cu (s) + 4HNO 3 (aq) ——> Cu (NO 3) 2 (aq) + 2NO 2 (g) + 2H 2 O (l) 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. Formula and structure: The chemical formula of nitric acid is HNO 3.Its molecular formula is written as NHO 3 and its molar mass is 63.01 g/mol. Aqueous nitric acid, HNO 3(aq), however, is able to dissolve copper metal because nitrate, NO3 If 1.0 mole of copper(II) nitrate decomposes, how many moles of nitrogen dioxide would be formed? Available on GSA Contract (1) Featured Industry. Write the balanced chemical equations of the following word equations. Chemically, nitric acid is made by bubbling nitrogen dioxide into water. Properties Chemical. So the objective in this approach is to generate nitrogen dioxide. read more. You wouldn't actually get any Zn(NO3)2 until the solution is evaporated and the salt actually forms. (Although since 1983, pennies are actually made of zinc surrounded by a paper-thin copper foil to give them the traditional appearance of pennies.) In the reaction of Copper and Nitric acid, Copper nitrate, nitric oxide and water are produced. Cop-per nitrate. Thanks! CuO(s) + 2HNO3(aq) --> Cu(NO3)2(aq) + 2H2O(l) If the reaction is between CuO and citric acid, then the complete neutralization of the acid will produce copper citrate and water. There are two general statements that describe the behaviour of acidic oxides.

HNO3(aq) + NaOH(aq) --> NaNO3(aq) + H2O(l) For the reaction between any acid and base one of the products is water.To get the other product (salt) take the anion of the acid and the cation of the base and write the formula correctly If you are wanting only to remove the copper oxide and leave the copper intact, then simple ... 1 min hot water sonication in 0.1 M HCL. 3 years ago This is a redox equation. Nitric oxide (NO) has various functions in the body. I put 8 parts of nitric acid because there are two parts that form the oxide and six parts that form the copper nitrate. Bubbling it through hydrogen peroxide is much more efficient. Because copper is not oxidized by H+, it is inert to most acids. However, NO (a colorless gas) is what is actually given off and it immediately reacts with oxygen in the air to give NO2, giving the brownish gas that seems to be generated by this reaction. Aqua fortis, Engravers acid, Hydrogen nitrate, Red fuming nitric acid, RFNA, White fuming nitric acid (WFNA) Colorless, yellow, or red, fuming liquid with an acrid, suffocating odor. Formula Weight. The actual nitrogen oxide formed depends on the concentration and temperature of the acid. Send Gift Now Following the demonstration, students can practice using the electrochemical series to predict the outcome of reactions by combining half cells (from a standard textbook) to explain how magnesium and copper react with hydrochloric and nitric acids in the way they do. This reaction is a cheap source of nitrogen dioxide, which can be bubbled through water to generate nitric acid through the following reaction: . When anhydrous ammonia and nitric acid combine, the excess water is evaporated which forms the product of a solid called Ammonium Nitrate. Previous question Next question Get more help from Chegg.
