Copper sulfate (CuSO4) is not a binary compound of copper and sulfur but a compound of copper, sulfur, and oxygen. It can be made by electrolysis of copper with sulfuric acid: Cu + H2SO4 --> CuSO4 + H2
True. Copper can be isolated in useful amounts during electrolysis, where an electric current is passed through a solution containing copper ions, causing them to deposit on the cathode. This process is commonly used in industries to extract and purify copper.
The cathode, where the +ions in solution accept electrons and become neutral metal atoms.
Copper sulfate is a chemical compound.
The compound CuCl is called copper(I) chloride. In this compound, copper has a +1 oxidation state, and it is formed by the combination of copper and chlorine. Copper can also form a +2 oxidation state, leading to another compound called copper(II) chloride (CuCl₂).
Impure copper can be purified through a process called electrolysis, where an electric current is passed through a copper sulfate solution, causing pure copper to be deposited on the cathode. The impurities are left behind as sludge or dissolve into the solution.
During electrolysis of copper sulfate solution using copper electrodes, the blue color of the solution remains because copper ions from the copper sulfate solution plate onto the cathode, replacing the copper atoms in the electrode. This does not change the color of the solution as the copper ions remain in solution, maintaining the blue color.
The color change in copper sulfate solution during electrolysis occurs because copper ions from the solution are attracted to the cathode, where they are reduced to form solid copper metal. This causes the solution to turn from blue to clear as the copper ions are removed.
The blue substance left in the solution after electrolysis with copper electrodes in a sodium carbonate solution is likely copper(II) carbonate. This forms as a solid product of the reaction between the copper electrode and the carbonate ions present in the solution.

Copper is refined through a process called electrolysis, which involves passing an electric current through a solution of copper sulfate. The key steps in the refining process include crushing and grinding the ore, smelting to remove impurities, converting the copper matte into blister copper, and finally electrolysis to produce pure copper cathodes.
Water is not used in the electrolysis of copper permanganate solution because water will compete as an electrolyte and interfere with the desired redox reactions happening at the electrodes. Using water as an electrolyte would form other byproducts instead of the intended products of the copper permanganate electrolysis. This could lead to inefficient and unpredictable results in the process.
The electrolysis of copper sulfate involves passing an electric current through a solution of copper sulfate, which contains copper (II) ions and sulfate ions. At the anode, copper (II) ions are discharged as copper metal, which coats the cathode. This process allows for the purification and electroplating of copper.
You can separate powdered copper sulfate and powdered copper in a solution through filtration. Copper sulfate is water-soluble and will dissolve in water, while copper metal will not dissolve and can be collected by filtering the solution. Copper can also be separated from copper sulfate by electrolysis, where an electric current is passed through the solution.
The method of extracting copper from an ore using electricity is called electrolysis. In this process, an electric current is passed through a solution containing copper ions from the ore, causing the copper to be deposited onto the cathode.
Yes, electrolysis can be used to separate copper from its ore. The process involves passing an electric current through a copper-containing solution, causing the copper ions to migrate and plate onto a cathode. This allows for the separation of pure copper from its ore.
