化学实验中使用不干净的仪器,会影响实验效果,甚至让实验者观察到错误现象,归纳、推理出错误结论。因此,笔者在化学实验中采用选择合适的洗涤剂、掌握洗涤玻璃仪器的操作方法、及时洗涤玻璃仪器等措施,排除影响实验效果的干扰因素,从而提高化学实验效果。 The use of unclean equipment in chemical experiments will affect the experimental results, and even allow the experimenter to observe the wrong phenomena and induce and infer the wrong conclusions. Therefore, the author in the chemical experiments using the appropriate choice of detergent, washing glass equipment master the operation method, timely washing glass equipment and other measures to exclude interference factors that affect the experimental results, thereby enhancing the effectiveness of chemical experiments.
