Na_2O_2与CO_2气体的反应在高师教材(见北师大等编《无机化学》下册652页)和(中学教材(见高中化学上册86页)都列出了反应方程式。但怎样验证这个反应不仅中学教材没有介绍,而且高师实验教材(如北师大等编《无机化学实验》)也未提及。由于这个反应能产生氧气,所以在防毒面具、高空飞行和潜水艇中用作二氧化碳的吸收和供氧。学生对这一
The reaction of Na 2 O 2 with CO 2 gas is listed in the textbooks for teachers’ colleges (see the “Inorganic Chemistry” in the next volume of the Beijing Normal University, etc., page 652) and in the middle school textbooks (see the high school chemistry book on page 86), but how to verify this reaction is not only The teaching materials for secondary schools were not introduced, and experimental textbooks for teachers’ colleges (such as the “Inorganic Chemistry Experiments” edited by Beijing Normal University, etc.) were not mentioned. Since this reaction can produce oxygen, it is used as a carbon dioxide absorber in gas masks, high-altitude flights and submarines. And oxygen for students.
