1. A Simple Daniell Cell
Complete the diagram below by writing in formulas for the composition of
the electrodes and of the ions in the solutions. Place these formulas near the
appropriate arrows leading into the solutions. Also indicate the electric charge
which is produced by a (+) or () sign near the top of each electrode.
e) Why must there be actual contact of the two solutions?
f) What is the half-reaction taking place at the negative electrode?
g) What is the half-reaction taking place at the positive electrode?
h) What is the overall cell reaction?
i)
What is the calculated standard potential of the Daniell cell?
j) How would you adjust the concentrations of the Cu²+ and of the Zn2+ in the
Daniell cell in order to obtain the maximum voltage possible?
Answer the following questions regarding the Daniell cell you have drawn in your
notebook.
