Popis: Benzoylacetanilide (BAA) forms violet colored complex Fe(BAA) 3 with Fe(III) in 60% alcohol with λmax at 540 nm. The stability constant (log K ) and free energy of formation of the complex at 20 °C are log K = 7.8 ± 0.1 and Δ F = −10.53 kcal / mole , respectively. The molar adsorptivity, sensitivity, effect of diverse ions in spectrophotometric determination of iron have also been investigated.
