Determination of the Stability Constant of Vanadium (V) with Alaine
Authors
Abstract:
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 constant of VO2Y was determined as log KVO2Y=11.32±0.35 at 25±0.1 °C and I=1 mol per liter of sodium perchlorate. The protonation constant of alanine was also determined poteniumetrically under above condition.

Spectrophotometric determination of the stability constant of vanadium(v)-p-chloro-N-phenyl-p-chlorobenzo- hydroxamic acid complex
The stability constant of the complex vanadium(v) p-chloro-N-Phenyl-p-chlorobenzohydroxamic acid was determined spectrophotometrically. The ligand p-chloro-N-phenyl-p-chloro-benzohydroxamic acid abbreviated in this paper as PCNPPCBHA was synthesized by the coupling of equimolar solutions of p-chlorobenzoyl chloride and freshly prepared p-chloro-ß-phenyl hydroxylamine; in which the later was pre...

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
