250 beaker
150 beaker
DC power pack (set to 12v) and connecting leads
croc clips
Ammeter
Rheostat
Stop clock
Balance
Hot-air blower, such as a hair drier (to dry electrode)
Emery paper for electrodes
Copper foil electrodes X2
copper(II) sulfate solution 1.0 M (200cc)
Propanone (about 200cc) (To clean electrode)
when rheostat heat up with high voltage, resistance increase
