The results obtained in this experiment are recorded in the table below.
|Type of electrochemical cell||Voltage (mV)|
*The above readings are the average obtained after 5 trials.
For the zinc-copper cell, 100 millivolts of electricity is produced.
For the lead-copper cell, 501 millivolts of electricity is produced.
For the lead-zinc cell, 489 millivolts of electricity is produced.
Students should be careful as they are dealing with electricity and chemical reactions in this experiment. Adult supervision required at all times.
