Ion Specific Molar Conductivity And Resistance

  1. Nov 29, 2012 #1
    1. Hi, basically I'm trying to find an equation to find ion specific molar conductivity of salt water flowing between electrodes.



    2. Relevant equations

    resistivity: rho = RA/L
    conductivity: kappa = 1/rho
    conducitivity per unit concentration: lambda = conductivity/concentration

    this is ion specific molar conducitivity with units of (s.m^2)/mol

    Dunno if this is correct

    Also to find the resistance of the ions using conductivity per unit concentration:

    gamma = L/lambda A

    Where A and L are the area of the electrodes and length respectively. Is this correct or am I totally wrong?

    Do ions have resistance associated with them according to their movement?

    Thanks!
