1. Place the zinc nitrate solution into a beaker and connect the zinc electrode so that it is partially submerged in the solution.
2. Place copper (II) nitrate solution into the porous cup and connect a copper electrode so that it is partially submerged in the solution.
3. Connect each electrode up to the voltmeter. If the needle moves left, change the connection so that the needle moves right. Record your observations.
4. Remove the copper electrode and porous cup. Pour out the solution from the porous cup and thoroughly rinse and dry the porous cup.
5. Repeat steps 2 to 4 using nickel/nickel (II) nitrate and zinc/zinc nitrate.
6. Repeat steps 2 to 4 using iron/iron (II) nitrate and zinc/zinc nitrate.
7. Repeat steps 2 to 4 using silver/silver nitrate and zinc/zinc nitrate.
8. Remove the porous cup and pour out the contents of the beaker.
9. Place the porous cup back into the beaker and use iron/iron (II) nitrate.
10. Repeat steps 8-9 using nickel/nickel (II) nitrate in the beaker and silver/silver nitrate.
Record your predicted observations
