Define zinc and copper aqueous solutions

Reference no: EM13517653

First lab experiment - zinc and copper aqueous solutions were tested in a microscale cell well where the voltage reading was 1.04V. Solutions were each at about 5mL.

The second experiment - zinc and copper were tested again, this time at about 30mL of each and voltage read 1.07V. zinc and copper electrodes were used respectively.

Third Experiment - 4 beakers, 2 of each solutions were connected. Parallel hook up netted a .30V, 118microAmp. Series netted a 1.11V and 589microAmp.

For the first 2 experiments - Could the fact that the surface area of the electrode increased be responsible for the voltage increase? If not that, then why?

3rd Experiment - what is the difference in hook up and why does one increase the voltage and microAmp?
