【摘要】 在基础化学实验试题中,常会出现一些分析结果误差判断题,而分析结果误差往往是由于学生的实验操作失误导致的。本文旨在建立一种通过确定滴定分析错误信息,并依据错误信息和分析结果的正相关或负相关关系确定其对分析结果的影响结论的快速判断方法。更多还原

【Abstract】 There are sometimes several judgment questions about errors of analytical results which are resulted from the faulty operations of students in experimental questions of fundamental chemistry. In this paper a fast judgment method is established to judge the effects of errors of operation in titration on analytical results through discussing the possible positive or negative relationship analytical results and error messages from the faulty operations.更多还原
