Please enable Cookies and reload the page. In the case of a reaction between CuO and nitric acid, you will get copper(II) nitrate and water. Copper(II) nitrate is poisonous if swallowed. Nitric Acid, colorless, acidic liquid that has the chemical formula HNO3, Medieval alchemists called it aqua fortis strong water. please help me!!!!! Calculate the percent yield of this process if 1.235 g of copper produced 1.452 g of copper . At a temperature of 25? ii. Acid + metal oxide ---> salt + water Most metal oxides are bases (a base is a substance that can neutralise an acid), this means they will react with acids to form a salt and water. (Copper II Oxide reacting with Nitric Acid)CuO + 2 HNO3 -->to get (Copper Nitrate and Water)Cu(NO3)2 + H2O Nitric acid is made by the action of sulfuric acid on sodium nitrate it is also made by the catalytic oxidation of ammonia. Nitric acid reacts with copper according to the reaction: 4 HNO 3 (l) + Cu(s) ==> Cu(NO 3) 2 (s and aq) + 2 NO 2 (g) + 2 H 2 O(l) The copper nitrate salt that forms is a deep blue color.

I put 8 parts of nitric acid because there are two parts that form the oxide and six parts that form the copper nitrate. There is also a second reaction, where NO reacts with oxygen in the air to form NO2, a very, very, very poisonous reddish-brown gas, but that's not part of the copper + nitric acid … (b) Calculate the moles of calcium oxide and nitric acid. You may need to download version 2.0 now from the Chrome Web Store. Close. Copper metal + nitric acid => copper nitrate + HNO3 copper reacts to give copper nitrate, nitrous oxides and water. The characteristics of copper, and the reaction of the metal with nitric acid The characteristics of copper, and the reaction of the metal with nitric acid Stable metal Vs. Strong oxidizer. In strong acid with very little water the nitrate ion will oxidize and dissolve the copper into the solution as copper nitrate, water, and red-brown Nitrogen Dioxide fumes. Copper reacts with nitric acid according to the following reaction: 3 Cu (s) + 8 HNO3 (aq) --> 3 Cu(NO3)2 (aq) + 2 NO (g) + 4 H2O (l) If an pre 1982 copper penny contains 3.10 grams of copper, what volume of 8.00 M nitric acid is glass cylinder; copper disk; dropper bottle of concentrated nitric acid; 100 mm watch glass; Procedure . 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. 2. changing copper(II) nitrate to copper(II) hydroxide (Unless specifically stated do not assume water is a reactant or product; often it is only a medium in which the reaction occurs.) (Don’t breathe this either). Copper nitrate is employed in various applications. Vous pouvez modifier vos choix à tout moment dans vos paramètres de vie privée. asked by Raj on October 28, 2007; Chemistry Equation(again) 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. Perhaps, less complex is to quote Wikipedia on the mechanics of the interaction between Nitric oxide and oxygen: When exposed to oxygen, nitric oxide … 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. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. View Lab Report - Zola lab 3 from CHEM 1211K at Georgia Institute Of Technology. Copper is an essential elements in plants and animals as it is required for the normal functioning of more than 30 enzymes. Copper and dilute nitric acid reaction give nitric oxide(NO), copper nitrate( Cu(NO 3) 2), and water as products. Chemically, nitric acid is made by bubbling nitrogen dioxide into water. The recycling of nitric acid and copper nitrate contained in an industrial effluent was studied.
