0copper will not displace hydrogen from an acid due to its low position in the electrochemical series ecs. however you can use copper with concentrated sulphuric acid to make copper sulphate. this reaction actually occurs in two stages. first the sulphuric acid oxidises the copper to cupric oxide then this reacts to form copper..

Read MoreCopper oxide is a completely different substance than copper, so naturally, it behaves differently when placed in sulfuric acid. substances lose their chemical properties when bonded with another element or compound.
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 copperii oxide.
Read MoreDont forget in this case, sulfuric acid is dibasic and has 2 h ions, so can use one to contribute to the water molecule formed. in the case of a monobasic acid like hcl, 2mols of hcl would have to be used to neutralise every mole of c.
Read More3excess copper oxide must be added to warm dilute sulfuric acid warmed using a water bath, which will react to produce a blue solution of the salt copperii sulfate. the solution then needs to be filtered using filter paper and evaporated using an evaporating basin and bunsen burner, followed by final drying using a watch glass to allow all the water to evaporate.

Read MoreThe effect of ammonia and complexones on the kinetics of copperii 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.
Read MoreIn oxide copper heap structures, the flow of sulfuric acid has a greater reducing effect on the friction angle of ore particles due to disintegration of particl.
Read MoreNickel ores the method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore the amount of sulfuric acid required is much higher than for copper ores as high as 1,000 kg of acid per tonne of or.

Read MoreNitric acid results show a roughly constant proportionality between the amount of 209po removed and the amount of copper removed. concentrated nitric acid was the most successful at removing the 209po contamination and the greatest quantity of copper was removed as well. dilute nitric removed less 209po and less copper in similar proportions.
Read MoreCopper oxidation in 110 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 copperi 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 ...
Read MoreThe leaching behavior of copper from cu 2 o in h 2 so 4 solution was investigated to establish the leaching process for cathode powders produced by the recycling of waste printed circuit boards. when air was not introduced in sulfuric acid solution, the dissolution of copper from cu 2 o was inhibited by the formation of elemental copper cu 0.the dissociated cuprous ions cu transformed ...
