Na2O2与CO2的实验在苏教版《化学1》中只有一个方程式,但过氧化钠一直是中学化学中一种重要的过氧化物,CO2与Na2O2反应的实验不但可以培养学生学习化学的兴趣,而且可以使学生对这块内容的理解更加深刻。该实验许多中学教师进行了改进,但基本上以定性为主,因此要整合过氧化钠的多种性质,从定量角度得出方程式中气体量的关系就比较困难,授课教师也只能根据氧化还原的基本规律
The experiment of Na2O2 and CO2 has only one equation in the Sujiao edition “Chemistry 1”, but sodium peroxide has always been an important peroxide in middle school chemistry. The experiment of CO2 and Na2O2 reaction can not only cultivate students’ interest in studying chemistry, And can make students more profound understanding of this piece of content. Many secondary school teachers in this experiment have made improvements, but they are basically qualitative. Therefore, to integrate various properties of sodium peroxide, it is difficult to draw a quantitative relationship between the amount of gas in the equation and the lecturer can only make experiments based on oxidation The basic principle of restoration
