Item Nickel (II)-citric acid complex formation in aqueous solution : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University(Massey University, 1979) Liddle, John RaymondTitrimetric analysis of solutions of nickel(II) chloride and citric acid, H 3 L, has led to the characterization of four complexes in the acidic pH range NiL - , NiHL, NiH 2 L + , and Nil 4- 2 . Equilibrium constants for the formation of these complexes are reported. Results from a visible spectrophotometric study are analysed in terms of these four complexes. The stability and possible structures of the complexes are discussed and compared with other nickel-carboxylic acid complexes.
