Variations with counterions concentration 𝐂^∘_Na+ of the experimental Λ^exp_NaChondro and theoretical Λ_NaChondro, Λ^𝑖_NaChondro 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 chondroitin sulfate in water at 25°C.
