Chemicals and Solutions: 

1M copper sulfate aq.

1M zinc sulfate aq.


small hydrometer cylinder

strips of copper and zinc

Digital readout voltmeter

piezo buzzer & switch

test leads


Fill a hydrometer cylinder half full with 1M Copper sulfate

Place a copper strip into the cylinder such that it both reachs the bottom of the cylinder and protrudes out the top of the cylinder.

Using an eyedropper carefully layer 0.1M zinc sulfate onto the copper sulfate

Place a short strip of zinc into the cylinder.  The zinc strip should not extend into the highly concentrated copper sulfate solution.

Attach alligator clips to the zinc and copper electrodes and connect the cell to the voltmeter

The cell can also be connected to a piezo buzzer and switch.
