Determination of the Stability Constant of Vanadium (V) with Alaine

Determination of the Stability Constant of Vanadium (V) with Alaine

Formation equilibria of dioxy vanadium (V) complex with alanine in acidic media (pH<2.3) has been investigated potentiometrically and spectrophotometrically. In this condition the 1:1 complex has the formula VO2Y, where Y¯ represent the fully dissociated aminocarboxylate anion. The stability cons...
