Abstract
Equilibria between the derivatives ofo-hydroxy naphthaldehyde and protons or bivalent metal ions have been investigated potentiometrically at constant ionic strength while varying the solvents in definite ratios (solvent: water). The method of Bjerrum and Calvin as modified by Irving and Rossotti (1954) has been used to find the values of\(\tilde n\) and pL. The formation constants of metal chelates have been calculated using a weighted least squares method. The values of\(S_{\min } = \chi ^2 \) have also been calculated. The order of stability constants is determined as Mg2+<Mn2+<Cd2+<Pb2+<Zn2+<Co2+<Ni2+<Cu2+<UO 2+2 Solvent effects on stability constants and comparative studies of both the derivatives ofo-hydroxy naphthaldehyde have been reported.
