What factors affect the mass of copper deposited onto the cathode in a copper electroplating cell?
Variables
Controlled
Concentration of Electrolyte
: Standard 1M Copper Sulfate (CuSO4) Solution
SA (Surface Area) Submerged
: **
pH of water:
Distilled water with a pH of 7 will be used.
Temperature of Electrolyte
: Electrolyte kept at room temperature
Purity of Copper
Equipment Used
Distance Between Electrodes
Electroplating Duration
Dependent
Mass of copper that has been deposited onto the cathode during the electroplating cell process.
Mass of Cu Deposited = Final Mass - Initial Mass (Cathode)
