Abstract In chemistry textbook for senior high school (Luke edition,2019), students can usually propose two sets of experimental programs for the removal of formaldehyde in the environment: using ammonia and acidic potassium permanganate solution. This paper discusses the reactants and reaction types in the two experimental schemes, and whether ammonia and acidic potassium permanganate solution can absorb formaldehyde gas in the environment, and through the analysis of the experimental teaching function, this paper puts forward some suggestions on using this material for experimental teaching.
