An electrochemical cell is set up as shown in the diagram below:

An electrochemical cell consisting of a beaker filled with a liquid electrolyte solution. Two vertical metal electrodes are suspended in the solution, connected by wires to a central voltmeter at the top, which displays a reading.

The order of reactivity of three metals is:

  • Magnesium (Most reactive)
  • Zinc
  • Copper (Least reactive)
a.

Which combination of metal electrodes from the list above would produce the highest voltage?

[2]
b.

The voltage produced by the cell depends on the type of electrodes and the type of electrolyte. Suggest one other factor that could affect the voltage produced.
