Alkali Hydroxide

The effect of the metal (Li, Na, K) on the kinetics and mechanism of the reaction of a copper single crystal in alkali hydroxide solutions was studied on the faces corresponding to the (100), (110), and (111) planes, with a special attention to the (100) plane. The differences in the kinetic behaviour are discussed in terms of the hydratability of the cations as well as of the physico-chemical characteristics of the hydroxide solutions, particularly their viscosity and the solubility of oxygen in them. Of the electrochemical parameters examined, only the E0 value is affected by the cation.

Mechanism Of The Reaction

The kinetics of the reactions of iron(III) with 6-methyl-2,4-heptanedione and 3,5-heptanedione to form the corresponding monocomplexes have been studied spectrophotometrically in the range 5 °C to 16 °C at I 25 mol l-1 in aqueous solution. In the proposed mechanism for the two complexes, the enol form reacts with the metal ion by parallel acid-independent and inverse-acid paths. The kinetic constants for both pathways have been calculated at five temperatures. Activation parameters have also been calculated. The results are consistent with an associative activation for Fe(H2O)63+ and dissociative activation for Fe(H2O)5(OH)2+. The differences in the results for the complexes of heptanediones studied are interpreted in terms of steric factors.
