Use the standard reduction potentials in volts: Cu^2+ --> Cu+ +0.16;
I2--> I- +0.54. calculate the value of E (in volts) for a cell in which the overall reaction is= 2Cu+ + I2--> 2Cu^2+ + 2I-

  • Chemistry - ,

    Cu^+ ==> Cu^2+ + e Eo = -0.16 v
    I2 + 2e = 2I^- Eo = 0.54 v
    ------------------------
    2Cu^+ + I2 ==> 2Cu^2+ + 2I^-
    Eocell = -0.16 + 0.54 = ??
    Using this process one does NOT multiply the Eo values by multipliers to make the electrons and coefficients balance.
