- 中文摘要: Anodic deposition of iodide ion on silver at 25° in aqueous (0.5M KNO3) and in 90% (w/w) ethanol-water (0.05M KClO4) solutions was studied galvanostatically. The exchange current density, transfer coefficient and the rate constants for the electrode reaction were evaluated. The experimental results revealed that the overall electrode reaction and the charge-transfer step was the same one, i.e.,Ag+I¯…AgI(s)+e¯, which might be assumed highly reversible as reflected by the exchange current density (i0) and transfer coefficient (α). The numerical values of the rate constants … and … at 25° were, in aqueous solution, 1.02×10¯5 and 2.88×10¯6, and in ethanol solution, 2.88×10¯5 and 6.3×10¯6 cm sec¯1, respectively.
