  1. 1.

    The equilibrium of complex formation of the hexaaqua ion of nickel (II) with pyridine and five of its derivatives in aqueous solution in the temperature interval from 5 to 45° was studied by the method of potentiometric titration.

  2. 2.

    Values of the concentration equilibrium constants, heats, and entropies of the reaction were obtained.
