Daniell Electrochemical Cell (Galvanic Cell) and the Gravity Galvanic Cell

In the original version of the Daniell cell a porous cup containing sulfuric acid and a zinc electrode is placed in a copper container filled with 1.0 M copper(II) sulfate solution.

Electrolytic Cell: Plating Copper on Copper Demonstration

Electrolytic Cell: two copper electrodes in 1.0 M CuSO4(aq) are connected to a D.C. Power Supply. When current is applied to the electrolysis cell copper(II) ions are reduced to copper atoms at the cathode and copper atoms are oxidized to copper(II) ions at the anode. The time to plate the metal is recorded along with the current (amps).
