Write equations to show the reaction between the following: (i) copper and concentrated nitric acid. Calculate the percentage yield of copper(II) nitrate. Complete step by step answer: Firstly, copper oxide is a compound formed by two elements copper and oxygen. Copper in the pure state cannot displace hydrogen atoms from acid. View solution > Write the balanced equation for the reaction in which copper is oxidized by concentrated nitric acid. 2HNO3 H2O + 2NO2 + [O] Prev Question Next Question . Medium. With copper, dilute nitric acid and concentrated nitric acid behave as an oxidizing acid. When the copper reacts with nitric acid to form copper $(II)$ nitrate, water and liberates gas, nitric oxide. The mechanics, in my opinion, likely involves a REDOX pathway with, for example, ${NO2}$ as a radical product in the case of concentrated Nitric acid proceeding, in this case, somewhat simply as follows: Action of cold and dilute Nitric acid on Copper. Write balanced equation and name the products formed when: (a) sodium hydrogencarbonate is added to nitric acid. View solution > 6) Could we use HCl to dissolve the copper metal. Copper reacts with dilute nitric acid according to the following equation: 3Cu (s)+8HNO3 (aq)3Cu (NO3)2 (aq)+2NO (g)+4H2O (l) If a copper penny weighing 3.040 g is dissolved in a small amount of nitric acid and the resultant solution is diluted to 45.0 mLmL with water, what is the molarity of the Cu (NO3)2Cu (NO3)2? Verified by Toppr. A mass of 15.3g of copper(II) nitrate is produced. The reaction is as follows: . Whereas the nitrate ion is being reduced to it's $+4$ and $+2$ states from its $+5$ state. Calculate the molarity of each of these solutions. In this reaction, copper is oxidized while nitric acid is reduced to nitric oxide. Cu(s) + 4HNO3(aq) --> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l). Answer (1 of 2): It forms Copper II Nitrate Cu(NO3)2 if reacted with nitric acid in any concentration - it's not the usual metal - acid reaction though, as it produces oxides of Nitrogen and water rather than hydrogen, due to the NO3- anions oxidising the metal. After the reaction, solution which contains Cu (NO 3) 2 is blue color. Sodium Sulfide. The diagram below shows a set-up that was used to prepare and collect a sample of nitric (V) acid. It depends on whether the nitric acid is concentrated or not. . Nitric acid is however an oxidising acid and so it'll oxidise the metal to the nitrate salt whilst be. View solution > View more.
