Potentiometric Study of Vanadyl Complexes of o-Hydroxyaceto phenone Oxime and its Substituted Derivatives

Department of Chemistry, Marathwada University, Aurangabad (Manuscript received 12 June 1972; revised 1 August 1972; accepted 20 September 1972) The metal-ligand stability constants of 1 : 1 and 1 : 2 complexes of vanadyl ion have been deter­mined at 30±1°C by the Bjerrum-Calvin pH titration technique as adopted by Irving and Rossotti in 75% dioxane and 25% water by volume and ionic strength 0.1 m. The linear relations between metal-ligand stability constant and proton ligand stability constant were examined for 1 : 1 and 1 :2 complexes of Vanadyl ion
