实验“化学反应速率的测定”的微型化探讨

Study on microscale about determination of the rate of chemical reaction

随着绿色化学理念的发展,化学实验的微型化设计受到了越来越多的关注。微型化学实验是利用尽可能少的化学试剂获得明显、清晰的反应结果和信息的实验方法,具有试剂使用量少、实验过程安全、环保等特点,有助于学生树立绿色化学的意识和理念。通过对经典实验“化学反应速率的测定”的微型化探讨,改进了实验内容,减少了试剂用量,降低了污染排放,提高了学生的参与度,并保证了实验教学的效果。

With the development of the concept of green chemistry,the microscale design of chemical experiments has received more and more attention.Micro chemistry experiment is an experimental method that uses as few chemical reagents as possible to obtain obvious and clear reaction results and information.It has the characteristics of low reagent usage,safe experimental process,and environmental protection,which helps students establish the awareness and concept of green chemistry.Through the microscale of the classic experiment“Determination of the rate of chemical reaction”,the experiment content is improved,the amount of reagents is reduced,the pollution emission is reduced,the participation of students is improved,and the effect of experimental teaching is guaranteed.
