of dicationic ionic liquids based on 3‑methylpyridinium and inorganic anions in acetonitrile. The Lee–Wheaton procedure is used to calculate constants Ka of ion association, the limiting molar electrical conductivity (λ0), and the Gibbs energy of association (ΔG) in solutions. It is shown that the nature and size of the anion are a key influence on the association of the studied ionic liquids. It is
