摘要
微型化学实验是体现绿色化学理念、培养创新人才的一种有效方法.介绍2个基于硫酸铜晶体设计的微型实验,硫酸铜晶体中水质量分数的测定和比色法测硫酸铜溶液的质量浓度.实践表明,微型化学实验可以调动学生的积极性,激发学生的学习动力.
Microscale chemical experiment is an available method, embodying the idea of green chemistry and fostering talent of innovation. Two cases of experimental design on copper sulfate crystal are provided, determination of water in the copper sulfate crystal by weight method and the concentration of the copper sulfate solution by colorimetric method. It is shown that some experiences on the desige of microscale chemical experiment can mobilize the interest of student in learning, stumulate the curiosity of students.
