摘要
利用SPSS 25.0统计软件对"蓝瓶子"实验进行正交实验设计,通过统计学分析得出最佳实验条件。利用氧化还原传感器(ORP)对"蓝瓶子"振荡体系的电极电势变化曲线进行分析,并针对蓝色的产生和消失过程设计3组对比实验深入探究,阐明其反应原理,意在引导学生深刻理解趣味实验现象背后的微观反应本质。
This paper used SPSS 25.0 statistical software to carry out orthogonal experimental design for the"blue bottle"experiment,and obtained the best experimental conditions through statistical analysis.The redox sensor(ORP)was used to analyze the electrode potential change curve of the"blue bottle"oscillation system,and three sets of comparative experiments were designed for the production and disappearance of blue to clarify the reaction principle,which was intended to guide students to understand deeply the nature of the micro-reaction behind the interesting experimental phenomena.
