Conductometric determination of formation constants of tris(2-pyridyl)methylamine and titanium (III) in water-acetonitryl mixture.
A conductance study of the interaction between titanium (III) cation and tris(2-pyridyl) methylamine (tpm), in water-acetonitrile mixtures was carried out at various temperatures. The formation constants of the resulting 1:1 complexes were determined from the molar conductance-mole ratio data. The s...

A conductance study of the interaction between titanium (III) cation and tris(2-pyridyl) methylamine (tpm), in water-acetonitrile mixtures was carried out at various temperatures. The formation constants of the resulting 1:1 complexes were determined from the molar conductance-mole ratio data. The stability constants of 1:1 (M:L) complexes of tpm with titanium (III) cation, the Gibbs standard free energies (ΔGc o{script}), the standard enthalpy changes (ΔHc o{script}) and the standard entropy changes (ΔSc o{script}) for the formation of these complexes in acetonitrile-water (AN-H2O) binary mixtures have been determined conductometrically.
