Answer to Question #249323 in General Chemistry for mhs

Question

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)

2. Calculate the electrode potential generated by the cell in the given notation:

Al(s)l Al3+(aq) ll I 2(s) l I – 1(aq) When [Al+3] = 4.0 x 10 -3 M and [I – 1 ] = 0.010 M
