  • you need to check your reference for Eo’s aqainst mine….

    if there is a difference….

    use yours

    Sn(s —> 3Sn2+ Eo = + 0.137

    NO3–(aq ) + 4 H+(aq) + 3 e– –> NO(g) + 2 H2O(l) Eo = + 0.956

    regardless of the number of moles needed to balance the equation, the Eo remains the same:

    Eo = + 0.137 & Eo = + 0.956 = 1.093 volts

  • 3sn
