Answers 1 - 5 Answers 1 - 5 1. The difference is “ ° ” - indicating 25°C and 1 M concentrations (1) 2. Voltages can be increased by arranging cells in series (1) (or changing concentrations) 3. “A measure of the tendency of a given half- reaction to occur as a reduction” (1) 4. The half-cell with the greater reduction potential will gain electrons (1) 5. The Cu half-cell has the greater reduction potential (1), since it is gaining electrons (1) /6

Answers 6 - 10 Answers 6 - 10 6. The Fe half-cell has the greater reduction potential (1) 7. E°cell = E°reduced - E°oxidized (1) (E°cell = standard reduction potential of substance reduced - standard reduction potential of substance oxidized) 8. 0.62 V (1) 9. There is no way to measure the standard reduction potential of an isolated half-cell (1) A reference/standard electrode is chosen (1) 10. Cu has the greatest reduction potential (1) /6
