主 题:Iodine Photochemical kinetics Oxidation-reduction
摘 要:The iodides can be oxidated to iodine by O;in air because of their lower redox potential. In an acidic solution, this reaction can be accelerated by ultraviolet light. Because the iodine yielded from potassium iodide by light irradiating solution can react with other oxidizer components, the iodine is constantly consumed. When it arrives the terminal points of the reaction, the iodine appears. According to the reaction time of the iodine appearing the quantities of the components are determined. And the terminal points can be pointed out by the blue of the iodine-starch or potentiometric
