It is well known that the molar conductivity of hydrogen ([H.sup.+]) ions is 0.3498 [mol.sup.-1] [cm.sup.-1] which is much higher than hydroxide (O[H.sup.-]) of 0.1986 [mol.sup.-1] [cm.sup.-1] [29].
The molar conductivity, A, defined as the conductivity (in S/cm) divided by the molar concentration of the ion in the solution, is one parameter used to estimate the overall conductivity.
The mixed ligand chelates of Co(II) Ni(II) and Zn(II) ions with Schiff bases; N-(2-hydroxy)-1-naphthylaniline and N-(2 hydroxybenzylididine)-23-dimethylaniline have been prepared and characterized by using different tools; such as CHN elemental analyses molar conductivity magnetic moment measurements thermogravimetric analysis and spectroscopic techniques.
These new complexes have been characterized by elemental analyses, molar conductivity, magnetic susceptibility, IR, 1H-NMR, UV- Vis spectra and TGA techniques.
