The table can be used to determine if a given reaction will take
place. For example:
Zn(s) + Cu2+(aq) --> Zn2+(aq) + Cu(s)
1. Left-click on the reaction's two half equations.
Zn2+(aq) --> Zn(s) + 2e
Cu2+(aq) --> Cu(s) + 2e
2. Click on the 'Reverse' button of the equation you need to
reverse in order to make the overall equation have a positive
E0 value.
Zn2+(aq) --> Zn(s) + 2e
