What happens on the cathode during the electrolysis of a

2015/1/19I assume you are referring to the electrolysis of copper (II) sulfate with copper electrodes. During the electrolysis of copper (II) sulfate, or CuSO_4, the deposition of copper can be seen on the cathode; at the same time, the anode will be dissolved by the process. It is very important to make a distinction between the labelling of the cathode in electrolysis and in galvanic cells, as

Why Are Graphite Electrodes Used in Electrolysis?

The main reason that graphite electrodes are used in electrolysis is that graphite is an excellent conductor. The structure of graphite is such that it has a large number of electrons floating freely between the different layers of atoms (graphite bonds are formed of only three out of the four electron shells of the carbon atom, leaving the fourth electron to move freely).
