Theoretical Equations - Conductivity
Resistance = Resistivity(T,C) * (electrode separation distance / electrode area)
- There exists no self-consistent theory to explain the behavior of electrolytes for the whole
concentration range. < 0.001 N the Debye-Huckel Onsager equation is
Conductivity = 1/Resistivity s = 1/r (S/cm) = 1 / (Ohms*cm)
L= molar conductivity k = Debye parameter
Lo= limiting molar conductivity (at infinite dilution) y = viscosity coefficient of solvent
z = ionic valence of ions 1 and 2 N = Avagodro’s Number
e = electronic charge g = concentration of solution
e = dielectric constant of solvent
lo = limiting ionic equivalent conductance of ions 1 and 2
- For dilute solutions the limiting case serves well.
