Calculate the voltage generated by the following cell.
Zn(s)|Zn2+ (0.1M) || Ni2+(0.005M) |+ Ni(s)
A. Write the overall cell redox equation.
B. Label the anode and the cathode in the cell notation above.
C. Calculate the standard cell potential.
D. Use the Nernst equation to calculate the cell potential.
Homework Answers
All the questions has been answered clearly. For electro-chemical cells the convention to calculate the cell potential is by subtracting the anode potential from the cathode potential. The Nernst equation has been used to calculate all the values.
However the standard reduction potentials should have been supplied for answering such type of problems and the question was lacking that information.
