Quick review
What is a galvanic cell
Using the standard reduction potentials table to calculate the voltage of the cell
determining spontaneity of a redox reaction
3
Galvanic cells
- Produces electrical energy through circuit
- Separates the redox reaction
- Measures voltage --> the difference in reactivity between the 2 electrodes
- References the metal reactivity series and standard reduction potentials data

Multiple Choice
The galvanic cell shown below was set up in an experiment:
Zn(s) | Zn2+ \\ Cu2+ | Cu(s)
Which correctly shows the oxidation half equation for the galvanic cell?
Zn(s) + 2e- --> Zn2+
Zn(s) --> Zn2+ + 2e-
Cu(s) + 2e- --> Cu2+
Cu(s) --> Cu2+ + 2e-
5
Calculating voltage of a cell
Must use the reaction given and the standard reduction potentials data (from data sheet)
Steps:
1. Find the two half reactions on the table (reverse oxidation)
2. Add together

Multiple Choice
Using the same galvanic cell as before:
Zn(s) | Zn2+ \\ Cu2+ | Cu(s)
Determine the voltage of the galvanic cell.
