A galvanic cell consists of a chromium, Cr bar in a chromic sulfate solution, Cr2(SO4)3 containing 13 g and a silver, Ag bar in a silver sulfate solution (Ag2SO4 ) containing 37.8 g 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) Electrode potential of the cell.
(Note: when calculating the molarity do not include the spectator ions)
