Studies of Electrolytic Conductivity of Some Polyelectrolyte Solutions: Importance of the Dielectric Friction Effect at High Dilution

Table 3

Variations with counterions concentration 𝐂^∘_Na+ of the experimental Λ^exp_NaPSS and theoretical Λ_NaPSS, Λ^𝑖_NaPSS equivalent conductivities, of the degree of Na⁺ condensation (1−𝛼_C), of the apparent charge number 𝑍_ap, and of the dielectric frictions in absence (𝛽^df) and in presence (𝛽^dfi) of interference, in the case of sodium polystyrene sulphonate in water at 25°C. Distinction between Manning concentration regime and Ostwald concentration regime.
