波动反应(Oscillating Reaction)是反应混合物在反应历程中两种中间体非活化络合物)的浓度显示波动变换的结果。铈(Ⅳ)盐催化的KBrO_3-CH_2(CO_2H)_2—KBr—H_2SO_4混合液,反应进行过程中的颜色变化为:黄色—无色—黄色……这种颜色的周期变换用计时法记录(见表1)色波能持续良久(注:色波指不同颜色出现交替时两相邻波谷间时间的间隔)。
The Oscillating Reaction is the result of a fluctuating shift in the concentration of the two intermediate inactive complexes in the reaction mixture during the reaction. The color change of KBrO_3-CH_2 (CO_2H) _2-KBr-H_2SO_4 catalyzed by cerium (Ⅳ) salt during the reaction is yellow-colorless-yellow ... The periodic transformation of this color is recorded by the timekeeping method Table 1) The color wave can last a long time (Note: The color wave refers to the alternation of different colors when the interval between two adjacent wave troughs).
