Question: 11 Four students prepared hydrated copper(II) sulfate by adding an excess of dilute sulfuric acid to copper(II)oxide. Each student used a different mass of copper(II)oxide. dilute sulfuric acid Cuo M = 80 Mr = 250 After the copper(II) sulfate had crystallised the students dried and weighed the crystals.
2:42 practical: prepare a sample of pure, dry hydrated copper(II) sulfate crystals starting from copper(II) oxide Excess Solid Method : Preparing pure dry crystals of copper sulfate (CuSO 4 ) from copper oxide (CuO) and sulfuric acid (H 2 SO 4 )
The leaching behavior of an Iranian copper oxide ore in sulphuric acid was investigated in detail to evaluate the influence of various factors, to optimize the dissolution conditions and to determine the kinetics of the leaching. The results indied that the increase in the leaching time and temperature enhanced the leaching rate of copper.
Aug 02, 2013 · Under these conditions, it has been found that sulfuric acid leaching is generally quite successful in recovering a large percentage of copper from copper oxide minerals, closely approaching the values for the specific minerals as shown in Tables 1 .

excess of copper (II) oxide is added to dilute sulfuric acid to make crystals of hydrated copper(II) processes listed may be used to obtain crystals of hydrated copper (II) sulfate.
Excess 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 copper(II) 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 ...
which two processes are involved in the preparation of copper sulphate from dilute sulphuric acid and an excess of copper oxide? explain.
Aug 21, 2020 · Copper(I) ions in solution disproportionate to give copper(II) ions and a precipitate of copper. The reaction is: Any attempt to produce a simple copper(I) compound in solution results in this happening. For example, if you react copper(I) oxide with hot dilute sulfuric acid, you might expect to get a solution of copper(I) sulfate and water ...
Concentrated sulphuric acid is added drop wise to a crystal of hydrated capper sulphate. Copper sulphide is treated with dilute hydrochloric acid. Excess of chlorine gas is reacted with ammonia gas. A few drops of dilute hydrochloric acid are added to silver nitrate solution, followed by addition of ammonium hydroxide solution.
Clearly the copper oxide is in excess, so the sulfuric acid is the limiting reactant, because you would need moles of the acid (only got mol) to react with all 10 g ( mol) of the copper oxide.
Oct 15, 2009 · Copper (II) oxide is a basic oxide, so it dissolves in mineral acids according to the general reaction : (1) CuO(s) + 2HX → CuX 2 + H 2 O In case of hydrochloric acid, sulfuric acid or nitric acid the reaction becomes: (2) CuO + 2HNO 3 → Cu(NO 3 ) 2 + H 2 O (3) CuO + 2HCl → CuCl 2 + H 2 O (4) CuO + H 2 SO 4 → CuSO 4 + H 2 O
For example, the blue copper salt copper(II) sulfate, commonly used for electroplating and as a fungicide, is prepared by the reaction of copper(II) oxide with sulfuric acid: Sulfuric acidWikipedia Zinc oxide, bismuth trioxide, and copper(II) oxide can be added for influencing the thermal expansion; unlike the alkali oxides, these lower the ...
The BHP smelter at San Manuel produces 450,000 gallons of sulfuric acid a day, or enough to fill 12,500 rail cars or 52,000 trucks every year. BHP Copper uses 18 percent of the sulfuric acid it makes for leaching its own oxide ore. Another 40 percent of its sulfuric acid production is sold to other mining companies for their leaching operations.
