Silver iodide reaction kinetics

The growth kinetics of this process are reported to be second order and surface reaction controlled. The precipitation of silver iodide in ethanol by the reaction... [Pg.332]

The application of surface-enhanced Raman spectroscopy (SERS) for monitoring redox and other processes at metal-solution interfaces is illustrated by means of some recent results obtained in our laboratory. The detection of adsorbed species present at outer- as well as inner-sphere reaction sites is noted. The influence of surface interaction effects on the SER spectra of adsorbed redox couples is discussed with a view towards utilizing the frequency-potential dependence of oxidation-state sensitive vibrational modes as a criterion of reactant-surface electronic coupling effects. Illustrative data are presented for Ru(NH3)63+/2+ adsorbed electrostatically to chloride-coated silver, and Fe(CN)63 /" bound to gold electrodes the latter couple appears to be valence delocalized under some conditions. The use of coupled SERS-rotating disk voltammetry measurements to examine the kinetics and mechanisms of irreversible and multistep electrochemical reactions is also discussed. Examples given are the outer- and inner-sphere one-electron reductions of Co(III) and Cr(III) complexes at silver, and the oxidation of carbon monoxide and iodide at gold electrodes. [Pg.135]

Donnan, from Laplace s theory of the internal pressure of liquids, arrived at a theory of negative surface tension which was supposed to explain why substances disperse to form colloidal rather than true solutions, a minimum size of particle being stable. Donnan and Barker investigated adsorption (see p. 742), Donnan and Le Rossignol the kinetics of the reaction between ferri-cyanide and iodide (see p. 660), and Donnan and Miss K. A, Burke the kinetics of the reaction between silver nitrate and alkyl iodides. [Pg.743]
