江苏省海安县教师进修学校(226600)周永生说本刊91年第2期发表的《Na_2O_2和CO_2反应的实验改进》一文中提出将生成的CO_2通过装有浓H_2SO_4的洗气瓶,以除去反应中产生的水蒸汽,再通过装有Na_2O_2的二通管,使其反应。我认为该文忽视了此反应的一个重要条
Hai’an County Teachers’ Training School of Jiangsu Province (226600) Zhou Yongsheng said that the article “Experimental Improvement of Na 2 O 2 and CO 2 Reactions” published in the 2nd issue of the journal in the year 91 proposes that the generated CO 2 should be removed through a scrubber with concentrated H 2 SO 4 to remove it. The water vapor generated in the reaction passes through a two-way tube containing Na 2 O 2 to react. I think this article ignores an important part of this reaction
