When an electrolyte is dissolved into a solution forming an electrolytic solution and the electrodes from an external energy or current source are immersed into the electrolytic solution. Then the Cations of the electrolyte gets attracted to the cathode and anions to the anode. Then the anions loose their electrons to the anode and cations get the deficient electron from the cathode thus creating a flow of electrons through the external energy source thus exchanging the atoms and charges by utilizing the energy from the external energy source. This process is called the Electrolysis.
For example:
When the electrolyte copper sulfate (CuSO4) is dissolved into water it gives Cation Cu++ and Anion SO4– – which moves freely in the solution. Now if we immerse the positive and negative terminals of a battery into the solution then the Cation Cu++ gets attracted to the cathode exchanging the electron from the cathode and Anion SO4– – gets attracted to the anode exchanging the electrons to the anode. This process causes the deposition of copper at Cathode. And the energy for the whole process is supplied by the Battery through which the current flow.
