In our last post: Electrolysis of Some Typical Electrolytes (Part I) , we studied the electrolysis of acidified water, dilute sodium chloride and brine under different conditions. Here, we will be looking at the electrolysis of copper (II) tetraoxosulphate (VI), CuSO4, solution. In solution, copper (II) tetraoxosulphate (VI) undergoes complete ionization to form copper (II) ions, Cu2+, and tetraoxosulphate (VI) ions, SO4--, according to the equation: CuSO4(aq) ----> Cu2+(aq) + SO4--(aq) .....................(i) Note that the two minus signs attached to the SO4 stand for 2- Electrolysis of Dilute Copper (II) tetraoxosulphate (VI) Using Inert (Platinum or Carbon) Electrodes The ions present in copper (II) tetraoxosulpha...
