  • Type of solution used: Cu(NO3)2, Zn(NO3)2, Pb(NO3)2
  • The concentration of the each solution.

  • Dependant:
  • The mass change in the cathode and anode

  • Controlled
  • The amount of time
  • The metals used for both rods
  • The temperature of the solutions


  • Power supply
  • Voltmeter
  • Zinc and Copper metal rods
  • Circuit wire
  • Beakers
  • Salt Bridge
  • Sand Paper
  • Crocodile clips
  • Graduating Cylinder
  • Cu(NO3)2, Zn(NO3)2, Pb(NO3)2
  • Weight Scale


  • Set up a beaker with 300 mL of 1M Cu(NO3)2
  • Set up the voltmeter ...
