Always remember that Cu has +2 charge while CO3 has -2 charge. 3 Cu + 8 HNO3 –* 3 Cu (NO3)2 + 2 NO + 4 H2O The balanced equation seen on the top is what you attain when you place copper metal in concentrated nitric acid. (ii) Concentrated hydrochloric acid and Potassium permanganate solution. CU-7 Tatum-T Paragard T 380A Element 29 Cuprum ... To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. Balanced Equation for Copper and Nitric Acid, What_is_the_balanced_chemical_equation_for_when_solid_copper_is_added_to_nitric_acid_copper_2_nitrate_nitrogen_dioxide_and_water_are_produced. Enter all coefficients for the reagents and products including "1" or "0" whenever appropriate. Enter all coefficients for the reagents and products including "1" or "0" whenever appropriate. 1) Copper is oxidized by concentrated nitric acid. Because copper is not oxidized by H+, it is inert to most acids. Name the gas that is produced in each of the following cases. Be careful with the nitric acid: like other strong acids, it will sting if you get it on your skin and can damage clothing; unlike most other acids, it will also stain the affected area yellow. (v) Zinc sulphide and Dilute sulphuric acid. If some copper remains undissolved by the time the production of gas is finished, then put the beaker on the hot plates in the hoods to hasten the reaction. 1 Answer. Cu(s) + 4 HNO3(aq) â Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O (l) Then the ionic equation. Copper metal reacts with concentrated nitric acid according to the following balanced equation: 3Cu(s) + 8HNO3(aq) ¨ 3Cu(NO3)2(s) + 2NO(g) + 4H2O(l) Calculate the mass in grams of the excess reagent remaining after the complete reaction of 4.63 g of Cu with 9.26 g of HNO3. Write a balanced chemical equation for each of the following: (i) Action of cold and dilute Nitric acid on Copper. Copper - Cu. 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. The reaction here above is a double-displacement reaction. Actually, zinc ions are formed and the nitrate ions are left over from the nitric acid (which dissociates into ions in water). 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. Dilute nitric acid reacts with magnesium and produce magnesium nitrate and hydrogen gas as the product. First write a balanced molecular equation. (Copper II Oxide reacting with Nitric Acid)CuO + 2 HNO3 -->to get (Copper Nitrate and Water)Cu(NO3)2 + H2O magnesium oxide What is the word equation for copper plus hydrochloric acid? The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. So i know the equation looks something like this . Balance and classify the chemical equation for copper and nitric acid reacting to form copper (II) nitrate and hydrogen gas. Reaction of Copper with Nitric Acid -- (2 parts) Balance the following reaction equations. Cu ( s) + 4HNO 3 ( aq ) → Cu (NO 3) 2 ( aq) + 2NO 2 ( g) + 2H 2 O ( l) The following is from article by Richard Ramette (1) that contains Ira Remsen's quote about nitric acid acting upon copper. 1b. Cu(s) + 4H+ (aq) + 4NO3-(aq) â Cu2+(aq) + 2NO3- (aq) + 2NO2(g) + 2H2O . What was the weather in Pretoria on 14 February 2013? (iii) Preparation of methane from iodomethane. Answer Save. Relevance. Type of Chemical Reaction: For this reaction we have a chemical reaction. Word equation: Copper + Nitric acid â Copper (II) nitrate + Nitrogen dioxide + water. The more reactive copper in CuCO3 displaces the less reactive H in HNO3 to form copper (II) nitrate, water and carbon dioxide. Copyright © 2021 Multiply Media, LLC.
