A concentration cell consists of two Zn/Zn²* half cells. The electrolyte in compartment A is 0.100 M
Zn(NO3)2 and in compartment B is 0.101 M Zn(NO3)2. A salt bridge is made with a NaNO3 solution.
2.
a). Identify and balance the ½ reactions and write the overall balanced net ionic equation representing the
total cell reaction.
b). Draw a neat diagram to represent this cell, showing and labeling all necessary components including:
anode, cathode, electron flow, cation flow, anion flow and charge on the electrodes.
c). Write the shorthand cell notation for this cell.
d). What is the voltage of the cell at 25°C?
e). What is the voltage of the cell at 15°C?
f). What is AG at 25°C?
g). What is AG at 15°C?
h). Dilute the electrolyte in compartment A 100 fold (e.g. take 1 mL and add 99 mL's of water). What is
Ecell at 25°C?
i). Calculate AG for this diluted cell E at 25°C.
j). Assuming AHrxn= 0, calculate ASran
k). Calculate ASuniverse. Is it spontaneous? Why/why not?
