Homework Help: Non-standard cell potential problem

  1. Nov 16, 2007 #1
    1. The problem statement, all variables and given/known data

    Sn2+ + 2e- --> Sn(s) E standard = -0.14 V
    Tl+ + e- ---> Tl(s) E standard = -0.34 V

    find the standard cell potential.
    and, what the cell potential would be if concentration of each of the ionic species involved is 2.9mM. assume dilute ideal behaviour and standard conditions for gases involved.

    3. The attempt at a solution

    I found the standard potential to be: -0.14 - (-0.34) = 0.20V

    now, do i use the nernst equation for the next part of the question??
