Question

A voltaic cell is constructed, based on the following half reactions:

Cu⁺ (aq) + e^- -> Cu (s)

I₂ (s) + 2e^- -> 2 I^- (aq)

The cell is operated at 25°C with [Cu⁺] = 0.25 M and [I^-] = 3.5 M.

Which electrode is the anode?
Is the answer to (1) the same as it would be if the cell were operated under standard conditions?
If the [Cu⁺] = 0.15 M, at which concentration of I^- would the cell have a zero potential?
