  • electrolysis copper sulfate solution with copper carbon

    2021-3-10 · 4. The electrolysis of copper(II) sulfate solution. The electrolyte copper(II) sulfate provides a high concentration of copper(II) ions Cu 2 and sulfate ions SO 4 2– to carry the current during the electrolysis process. There are tiny concentrations of hydrogen ions H and hydroxide ions (OH –) from the self-ionisation of water itself but these can be ignored in this experiment.

    2020-12-1 · The production of a chemical reaction by passing an electric current through an electrolyte is called electrolysis. We know that an electrolyte contains ions which are charged. The positively charged ions are called cations because they are attracted to the cathode and the negatively charged ones are called anions because they are attracted to the anode.

  • Copper Mining and Production Processes Explained

    Leaching offers an alternative to copper mining. First the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore over a period of months dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
