Electrolysis of acidified copper sulphate solution with potassium electrodes????????

Dear student,.....The products of electrolysing copper sulfate solution with inert electrodes (potassium electrode) are copper metal and oxygen gas. Using the simple apparatus and inert carbon (potassium) electrodes, you can observe the products of the electrolysis of copper sulfate solution are (i) a copper deposit on the negative cathode electrode and (ii) oxygen gas at the positive anode electrode. This anode reaction differs from when you use copper electrodes . You have to fill the little test tubes with the electrolyte (dil. copper sulfate solution), hold the liquid in with your finger and carefully invert them over the nearly full electrolysis cell. The simple apparatu can be used with two inert wire electrodes. The blue colour fades as more and more copper is deposited, depleting the concentration of blue copper ion Cu2+ in solution....... Regards.
