potential difference

Perform a first-hand investigation and gather first-hand information to measure the difference in potential of different combinations of metals in an electrolyte solution.

Background information

Potential difference
The potential difference is the difference between two cell potentials of two metals. Which metal is more easily oxidised can be determined through the cell potential difference results.

To determine potential differences of metals, one metal must be chosen as an arbitrary zero reference. This metal becomes the standard cell potential.

Standard cell potential (Eo)
The standard cell potential is the ...
