Conductance G = 1/R (Siemens). Conductivity kappa = G * . Molar conductivity = kappa * 1000/C (S./mol). Upon dilution: kappa decreases (fewer ions per ), but increases (more dissociation per mole). For strong electrolytes, increases linearly with decreasing sqrt(C) — Debye-Huckel-Onsager equation. Lambda_m_{infinity} is found by extrapolation. For weak electrolytes, increases sharply near infinite dilution — cannot extrapolate. Use Kohlrausch's law. Degree of dissociation: alpha = \frac{Lambda_m}{Lambda_m_infinity}. Combined with Ostwald's dilution law: Ka = C*alpha^. H+ (349.6) and OH- (198) have anomalously high ionic conductivities due to the Grotthuss proton-hopping mechanism.
