The L-T.M.A.I. and L-T.E.A.I. have been synthesised and their dissociation constants are 7.943 × 10-10 and 1.413 × 10-10 respectively. The potentiometric studies show that these reagents form 1 : 1 complex with copper (II) and iron (II). The stability constants of copper complex and iron complex with L-T.M.A.I. are 5.75 and 6.05 respectively and for L-T.E.A.I., 5.97 and 6.215 respectively. The free energy of complex formation at 25°C are 7841 cals/mole and 8150 cals/mole for Cu(II) -L-T.M.A.I. and Fe(II) -L-T.M.A.I. respectively, whereas the free energy of the Cu(II) -L-T.E.A.I. and Fe(II) -L-T.E.A.I. are 8141 cals/mole and 8375 cals/mole respectively.
