A student sets up a simple chemical cell to measure potential difference, as shown in the diagram.
| Electrode X | Electrode Y | Electrolyte | |
|---|---|---|---|
| Combination 1 | Copper | Copper | Potassium nitrate solution |
| Combination 2 | Zinc | Zinc | Pure water |
| Combination 3 | Zinc | Copper | Potassium nitrate solution |
| Combination 4 | Zinc | Copper | Pure water |
Which combination of Electrode X, Electrode Y, and Electrolyte would not give a zero reading on the voltmeter?
Combination 1
Combination 2
Combination 3
Combination 4
