Determination of composition and stability of vanadium (5) complex with reagent of class of 2,7-bisazoderivative of chromotropic acid and 4-aminoantipyrine
Description
Complex formation of vanadium with reagent (Ant) of 2,7-bisazoderivative of chromotropic acid and 4-aminoantipyrine in water solutions is studied using spectrophotometry. Vanadium is shown to form with Ant complex with V5+:Ant=1:2 at pH4. Stability constant K=5.37·1016 is calculated, sensitivity and reaction selectivity are determined. Complex hypothetical structure is presented
