Decomposition of nitric acid 相关知识点: 试题来源: 解析 A。解析:当铜与硝酸反应时会生成硝酸铜,硝酸铜溶液呈蓝色,这是溶液颜色变化的主要原因。选项B,氧气的释放不会导致溶液呈现蓝色。选项C,水的产生也不会使溶液变成蓝色。选项D,硝酸的分解与溶液变成蓝色这一现象无关。
When copper (Cu) reacts with nitric acid (HNO₃), the reaction is often carried out under a certain temperature. Which English term is used to describe "reaction condition"? A. Product B. Reactant C. Catalyst D. The situation in which a reaction occurs ...
The nitrous acid reacts vigorously with the copper, and the etch rate increases as the etch progresses through the copper toward the substrate. A polymer and/or a nitrous acid scavenger can be included in the etching solution to confine the etching reaction to the region in which the nitrous...
A reaction between 7.0g of copper (II) oxide and 50ml of 2.0m nitric acid produces copper (ii) nitrate and water. What is the mass of excess reactant after reaction? Apr 24 2022 Sorry but I am unable to do calculations of this type which deal with molal solutions . That is without...
Nitrous acid can readily react with nitric acid to regenerate twice the original quantity of NO2 by the reaction, HNO2 + HNO3 → 2NO2 + H2O. In each cycle the quantity of NO2 and HNO2 is doubled. Citation Desai, M.N. and Rana, S.S. (1973), "INHIBITION OF THE CORROSION OF ...
The Copper Cycle CHEM 101 Lab-M/630 As an investigation of the copper cycle lab group 6 conducted an experiment on 6 October 2014 at Arizona State University laboratory that would demonstrate the cycle of reactions that copper (Cu) can produce when introduced to with other substances/reactant....
PURPOSE:To simultaneously analyze copper and lead and to remarkably reduce the man power, time and cost, by performing electrolysis of solution of copper alloy dissolved with nitric acid to both cathode and anode through the use of platinum electrodes, and separating the lead peroxide to the anode...
Name the gas produced when nitric acid is added to copper metal. Metals: Metals are elements that can be found on the left side of the periodic table. Most metals can react with acids in an oxidation-reduction reaction. This often results in the formation of a solution and a gas. ...
Cu2O3 is a strong oxidizing agent (for example, it displaces chlorine from hydrochloric acid). The chemical activity of copper is not high. The compact metal does not react with dry air or oxygen at temperatures below 185°C. A green film of basic carbonate forms on the surface of copper...
Makton et al.22 found the presence of citric acid enhanced Cu adsorption of polyethyleneimine (PEI) modified agarose from sodium acetate buffered solutions. However, to date, adsorption mechanisms of these amine adsorbents for HMIs from HMIs-OAs bi-solutes systems in contrast with single solute ...
