Question
A voltaic cell is constructed that uses the following half-cell
reactions:
Cu+(aq) + e- ----->Cu(s)
I2(s) + 2 e- ----->2 I-(aq)
The cell is operated at 298 K with [Cu+] = 0.25 M and
[I-] = 0.035 M. (a) Determine E for the cell at these concentrations.
(b) Which electrode is the anode of the cell?
(c) Is the answer to part (b) the same as it would be if the cell
were operated under standard conditions? (d) If [Cu+] were
equal to 0.15 M, at what concentration of I- would the cell
have zero potential?
