The formation of silicato complexes of aluminium in aqueous solution at pH 8 was studied by chromatography and flow injection analysis. Most of the aluminium formed anionic species with Al-0-Si bonds in monosilicic acid solution. A complex AzL6 (A = aluminium; L = Si in silicic acid) could be separated on a Sephadex G-50 column. The existence of mononuclear complexes of aluminium, AL3 and AL4, was suggested from an adsorption experiment on an anion-exchange resin.

The electrochemical behaviour of pure aluminium in aqueous KOH solutions has been examined by steady state and non-steady state techniques (impedance, potential pulse., potential scan). A surface free from oxide and hydroxide could not be established at any potential. The fall in the aluminium disso
The kinetics and mechanism of the reaction of complexation of chromium(II1) with 2-acetylcyclohexanone has been investigated spectrophotometrically in aqueous solution at 50ยฐC and ionic strength 0.5 mol dm-3 NaC104. The equilibrium constants of the complex have been determined. The mechanism propose
