Consider a galvanic cell based upon the following half reactions: Fe3+ + 3e- → Fe -0.0036 V Cu2+ + 2e- → Cu 0.34 V

How many of the following responses are true?

1. Increasing the mass of the Cu will change the initial potential of the cell

2. Fe is being oxidized during the reaction

3. Increasing the concentration of Cu2+ (assuming no volume change) will decrease the potential of the cell

4. Decreasing the concentration of Fe3+ (assuming no volume change) will decrease the potential of the cell

5. Adding equal amounts of water to both half reaction vessels will increase the potential of the cell
