摘要
按照《无机化学实验》教材中关于"四氧化三铅组成的测定"实验的方法,大部分学生难以得到正确的实验结果。该研究分析教材提供的实验方法和数据,提出新的实验方法和改进措施。结果表明,新方法更容易获得正确的实验结果。
Most of the students is difficult to get the correct results in the process of experiment about the composition of Pb3O4 in inorganic chemistry experiments. After improved on the method and its data, we put forward a new method for this experiment. According to this new method, correct result of this experiment can be obtained easily.
