化学能驱动的非平衡态变色
Chemical Fuel-Driven Non-Equilibrium Color Change
摘要
Abstract
We have introduced a general chemistry experiment with the title of"Chemical Fuel-Driven Non-Equilibrium Color Change".This experiment mainly includes the pH jump-induced color change reaction of methyl red based on tribromoacetic acid,and the exploration of its mechanism using a pH meter.Through the practice of this experiment,students can understand the concepts of thermodynamic equilibrium,kinetically controlled non-equilibrium,and dissipative non-equilibrium states,master the basic concepts of buffer solutions and pH indicators,as well as consolidate the usage of common experimental instruments.关键词
