A galvanic cell consists of a chromium, Cr bar in a chromic sulfate solution,
Cr2
(SO4
)3
containing 0.25 moles and a silver, Ag bar in a silver sulfate solution
(Ag2
SO4
) containing 0.35 moles in a 3 L solution. and a sodium sulfate
solution use as a salt bridge solution. The silver electrode is positive relative
to the chromium electrode. Write the cell half- reactions, overall reaction and
cell notation. Calculate the following:
A) Gibbs Free – Energy
B) Standard Gibbs Free – Energy
C) Electrode potential of the cell.
