Two simple cells are made using the same pair of metals as electrodes, but a different electrolyte in each cell. The two cells produce different voltages. What does this show?
The voltage of a cell depends only on the metals used as electrodes
The voltage of a cell depends only on the electrolyte that is used
The voltage of a cell depends on the volume of electrolyte that is used
The voltage of a cell depends on the electrolyte as well as the electrodes
