Copper oxidation in 1–10 M sulfuric acid solutions is studied using cyclic voltammetry and x-ray diffraction methods. Copper passivation is shown to be caused by the formation of a resistive porous layer of copper(I) oxide via an electrochemical mechanism. The primary product of the electrode reaction is unstable and, depending on the acid concentration, either enters chemical reactions with ...

The effect of ammonia and complexones on the kinetics of copper(II) oxide dissolution in aqueous solutions of sulfuric acid is studied. It is found that addition of complexones and ammonia to acidic media decreases the dissolution rate. Modeling of the dissolution kinetics shows that the inhibiting effect of complexing agents is caused by a decrease in the concentration of surface intermediate ...

2021-2-19 Copper salts can be made in a reaction of sulfuric acid and copper oxide. Small nuggets of pure copper. Mixing copper and sulfuric acid causes the copper to change properties and oxidize, or react. This oxidizing makes copper dissolve into copper compounds that form both hydrates and ions.

The copper was found to be cuprous oxide (Cu 2O) and ele-mental copper (Cu0) in the preliminary study. Only a few studies examined the leaching of cuprite (Cu 2O)7–10). In these studies, leaching tests were carried out using various solutions, such as sulfuric acid with ferric sul-fate7 ), sulfuric acid with perchloric acid8,9, and sulfuric acid
Read MoreOres containing cupric oxide, CuO, are commonly reacted with sulfuric acid to produce a copper containing material that is more easily processed. This process is known as sulfuric acid leaching. Write a balanced chemical equation for the reaction of cupric oxide with sulfuric acid. Cupric oxide is another name for copper(II) oxide.
