# Ion Specific Molar Conductivity And Resistance

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!
