Conclusions

  1. 1.

    The ionic association of salts of trinitromethane, dinitromethane, and gem-dinitroethane was studied in solution of methanol and ethanol by the method of electric conductivity. The dissociation constants of the ion pairs of the salts were calculated. It was found that these values are of the same order of magnitude in methanol and in ethanol.

  2. 2.

    The degree of association of the salts studied in methanol and ethanol, as a rule, does not depend on the nature of the cation and anion, which is evidence of the equalizing effect of these solvents.

  3. 3.

    On the basis of the data obtained on the electric conductivity we compared the solvating ability of methanol and ethanol with respect to the anions studied: trinitromethane, dinitroethane.

  4. 4.

    The interionic distances in the ion pairs were estimated.
