a. A second student tries to set up the experiment above, but mistakenly grabs a bottle of 0.1 M Sn(NO3)2 solution to use in the half-cell. The volumes of solutions in this cell are identical to the volumes in the sample cell above. Would the cell potential be greater than, less than, or equal to the cell potential of the standard cell? Justify your answer. b. Both cells can be used to power an electronic device. Will the second cell power the electronic device for the same time, a longer time, or a shorter time? Justify your answer.
