【摘要】 根据酸碱指示剂在碱性条件下显示不同的颜色以及美术中的调色原理,设计了一个可用于展示奇妙化学的简单实验。实验是以不同比例配制多种混合酸碱指示剂,加入NaOH溶液就可以得到多种颜色的溶液。实验准备过程中发现指示剂浓度、液体承装容器的形状、碱溶液浓度以及外界光源等因素与最后的展示效果都有关系。这样有趣过程既充分展示了实验室基本实验到应用于实际的过程,还体现了物理、化学、美术等多学科的原理在一个实验中的应用;这一有趣的探索过程展示出化学实验中的需要考虑多种因素的影响,也让同学们更加深入地理解化学实验的创新性和探究重要性,反映了在科研探究中应当采取的态度,对探索基于化学学科的"课程思政"和培养学生对化学实验的兴趣有着重要意义。更多还原

【Abstract】 According to different colors of solutions in the alkaline condition with acid-base indicators,and the principle of toning in the field of art,we designed a simple experiment to use in demonstration.In this experiment,by mixing various acid-base indicators in different proportions and adding them into NaOH,solutions at multitudinous colors can be obtained.Moreover,the influence of the concentration of indicators,containers,the concentration of base and external light source on the color of solutions was studied.The exploration process of this interesting experiment that embodies many exploration and innovation methods in chemistry experiments is reflected.The attitude we should take in scientific research and exploration is demonstrated.All of them are of great significance for exploring "Course Ideology and Politics"based on chemistry and cultivating students’ interest in chemical experiments.更多还原
