3. Then write an "addition line" below these and add the two half cell together to get the overall reaction (its is the net ionic reaction) and add the two half cell volts to get E<sup>o<sup>cell ( in Volts), the Volts of the overall reaction called the "cell". |

1. From the information from one's data table, what happened to the Voltage as the reaction occurring. 2. Why does the voltage decrease as the reaction occurs (Hint: Explain use information about energy). 3. What would the voltage be if/when the reaction "stops". Explain 4. What component of the cell would cause the cell to stop working and why would it happen? (Assume you can't change the alligator clips). 5. What would happen if you did not use the same metal as the metal ions in the half cell (in other words decided to use a dissimilar metals for the electrode?). 6. What is the phrase you memorize/remember to help you with creating these cells (both section). What does it mean? |
