2. In another experiment, Fischl used cadmium metal to form an electrode she can use for her voitaic cell. She wanted to determine the electric potential produced by the cadmium electrode (and 1.0 M of its corresponding electrolyte solution) with a Copper electrode in 0.10 M CuSO4 solution at 25 °C. Predict the following:

2. In another experiment, Fischl used cadmium metal to form an electrode she can use for her voitaic cell. She wanted to determine the
electric potential produced by the cadmium electrode (and 1.0 M of its corresponding electrolyte solution) with a Copper electrode in 0.10 M
CuSO4 solution at 25 °C. Predict the following:
a. OHR of the voltaic cell:
b. RHR of the voltaic cell:
Cd(s) → Cd^2+(aq)+ 2e-, Eo = + 0.40 V
c. Number of electrons i
Cu(s) → Cu^2+(aq)+ 2e-, Eo = - 0.34 V
d. Overall reaction for th
Cu^2+(ag) + 2e- → Cu(s), Eo = + 0.34 V
e. Standard cell potentia
Cd^2+(aq)+ 2e- → Cd(s), Eo = - 0.40 V
f. Theoretical Ecell:
%
g. If the measured Ecell was 0.50 V, calculate the percent error.
h. Oz suggested that they increase the concentration of CUSO4 solution used. What will be the effect on the measured potential?
