What is observed when copper sulphate solution is

In the aqueous solution, copper sulphate dissociates into its respective ions. On passing electric current, the copper ions (cations) move towards the cathode and get deposited as copper.Simultaneously, the sulphate ions (anions) move towards the anode. So, b lue colour of the solution disappears.

I was indeed using a CuSO4 concentration of 1M.

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).

During the electrolysis of copper [II] sulphate solution
