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.

Electrolysis: Electroplating: Electrolysis refers to the breaking apart from a molecule by the means of the electrochemical reaction. Electroplating refers to the passage of current through the solution with metal such that it gets deposited on one of the electrodes. Electrolysis is good for carrying out the non-spontaneous chemical reactions.

Electrolysis of Copper Sulfate. Whenever copper sulfate or CuSO 4 is added to water, it gets dissolved in the water. As CuSO 4 is an electrolyte, it splits into Cu + + (cation) and SO 4 − − (anion) ions and move freely in the solution. Now we will immerse two copper electrodes in that solution.

The potential required to oxidize Cl-ions to Cl 2 is -1.36 volts and the potential needed to reduce Na + ions to sodium metal is -2.71 volts. The battery used to drive this reaction must therefore have a potential of at least 4.07 volts. This example explains why the process is called electrolysis.The suffix -lysis comes from the Greek stem meaning to loosen or split up.
