Conductance G = 1/R (Siemens). Conductivity kappa = G * cell_constant (S/cm). Molar conductivity Lambda_m = kappa * 1000/C (S.cm^2/mol). Upon dilution: kappa decreases (fewer ions per cm^3), but Lambda_m increases (more dissociation per mole). For strong electrolytes, Lambda_m increases linearly with decreasing sqrt(C) — Debye-Huckel-Onsager equation. Lambda_m_infinity is found by extrapolation. For weak electrolytes, Lambda_m increases sharply near infinite dilution — cannot extrapolate. Use Kohlrausch's law. Degree of dissociation: alpha = Lambda_m/Lambda_m_infinity. Combined with Ostwald's dilution law: Ka = C*alpha^2/(1-alpha). H+ (349.6) and OH- (198) have anomalously high ionic conductivities due to the Grotthuss proton-hopping mechanism.
