一氧化碳与氢氧化钠的反应,在中学化学课本中曾多次出现,但均没设置实验。在教学中,补充做的二氧化碳与氢氧化钠反应的实验,大都是在水溶液中进行的。(例如,80年第4期《化学教育》第37页“氢氧化钠跟二氧化碳反应”一文所介绍的实验)。这样,就出现了如下两步反应:CO_2+H_2O=H_2CO_3,H_2CO_3+2NaOH The reaction of carbon monoxide with sodium hydroxide has appeared many times in chemistry textbooks in middle schools, but no experiments have been set up. In the teaching, the experiment of supplementing the reaction of carbon dioxide with sodium hydroxide was mostly carried out in aqueous solution. (For example, the experiment described in “Chemical Education”, p. 37, “Reaction of Sodium Hydroxide with Carbon Dioxide”, 80th Issue No. 4). In this way, the following two-step reaction occurs: CO_2+H_2O=H_2CO_3, H_2CO_3+2NaOH
