Abstract It's a universal phenomenon that the nucleophilic addition reaction of the highly active aldehyde or ketone with saturated sodium bisulfate solution can produce a white precipitate and exothermic phenomenon.However, acetaldehyde with hyperactivity is an exception.The editors of organic chemistry experimental teaching materials are not very familiar with this exception.In this paper, we expound the main reasons for this exception and propose an improved scheme for the experiment of the addition reaction of acetaldehyde with sodium bisulfite.
