Chemistry! AHHH!! redox reactions?

Posted by

A concentration cell consists of two Sn/Sn2+ half cells. The cell has a potential of 0.11 V at 25 degrees Celsius.

What is the ratio of the Sn^2+ concentrations in the two half-cells?

Thank you so much for all your help!!

    Sn + Sn2+ (x M) —–> Sn + Sn2+ (y M)

    Ecell = Eocell – (0.0591/2) log ([Sn2+ (y M)] / [Sn2+ (x M)])

    0.11 = 0 – (0.0296) log x

    log x = 0.11 / (-0.0296) = -3.7

    x = 10^-3.7 = 0.00019 = ([Sn2+ (y M)] / [Sn2+ (x M)]
