如今,数字化实验在化学实验中的应用越来越广泛。我们利用朗威DIsLab 6.8系统,在火柴硫成分检测中进行了应用,收到了很好的实验效果。在苏教版《实验化学》专题3“物质的检验与鉴别”一节中,有火柴中硫成分的检验实验。其鉴别方法是将火柴燃烧,生成的二氧化硫溶于水,用高锰酸钾溶液与 Nowadays, digital experiments are more and more widely used in chemical experiments. We use the Longway DIsLab 6.8 system, which has been used in the detection of sulfur content in matchstick and has received good experimental results. In the Soviet version of “Experimental Chemistry” topic 3 “material testing and identification ” section, there is a test match of sulfur components in the experiment. The identification method is to burn the match, the generated sulfur dioxide dissolved in water, with potassium permanganate solution and
