In a galvanic cell, one half-cell consists of
a cobalt strip dipped into a 1.00 M
solution of Co(NO3)2.
In the second half-cell,
solid palladium is in contact with a
1.00 M solution
of Pd(NO3)2. Pd is
observed to plate out as the galvanic cell operates, and the
initial cell voltage is measured to
be 1.231 V at 25°C.


(a) Write balanced equations for the half-reactions at the anode
and the cathode. Show electrons as e-. Use the smallest
integer coefficients possible and include states of matter in your
answers. If a box is not needed, leave it blank.

Half-reaction at anode (do not multiply by factor):
Half-reaction at cathode (do not multiply by factor):
(b) Calculate the standard reduction potential of
a Pd2+|Pd half-cell.
The standard reduction potential of
the Co2+|Co electrode
is -0.280 V.
