Electrolysis of Copper(II) Sulfate using inert electrodes

Expected observations:
Effervescence of colorless odorless gas (oxygen)
Formation of a solid at the cathode, where Copper(II) ion is reduced to form Copper atom.
Intensity of blue solution decreases as Copper(II) has been reduced to Copper atom.

Also, the pH of the solution decreases as the hydroxide ions are discharged while the hydrogen ions remain in solution, along with the sulfate ions.
