All the cathodes in the diagram

Anode of Electrolytic Cell

Cathode of the Electrolytic Cell

All Electrodes that are Negative

All Electrodes that are positive

Negative Electrode of the Electrolytic Cell

Which electrode(s) allow the electrons to flow back to the battery

2. Choose all that applies for the following diagram above: *

Electrochemical Cell A

Electrochemical Cell B

Spontaneous

Non- Spontaneous

Positive Volts

Negative Volts

Provides Free Energy

Requires Free Energy

Increase in entropy

Decrease in entropy

3. Using the same experimental set-up as question 1, determine the location of the following: *

Chemical species that is oxidized in the voltaic Cell

Chemical species that is oxidized in the electrolytic cell

Chemical species that is reduced in the electrolytic cell

Be+2

Cl-

Where Be (s) produced

Where Chlorine (g) is produced

4. What is the overall net ion reaction in the galvanic cell from this experiment? *

Be + 2Cl2 ---> BeCl2

BeCl2 ---> Be + 2Cl2

Mg + Mg+2 ----> 2Ag+ + Ag

2Ag+ + Ag ----> Mg + Mg+2

Mg + 2AgNO3 ---> Mg(NO3)2 + 2Ag

8. True Or False. The voltaic cell has enough Free Energy to "run" the electrolytic cell. *

True

False

9. If magnesium chloride was added to the upper left side of Electrochemical cell in the above experiment, what affect could it have on the electrolytic cell. *

There is more than one answer!

It would have no effect on the electrolytic cell

It it could decrease and or eventually stop the electrolytic cell.

It could start/increase the the electrolytic cell.

It could increase the production of Chlorine Gas.

It could decrease the production of Cl-

It could increase the production of Be(s)

It could decrease the production of Be (s)

Required
