True or False: It is OK to use wet glassware for the aspirin synthesis without potentially affecting your yield
vesna_86 [32]

Answer:

False

Explanation:

Laboratory synthesis of aspirin is done by the acetylation of salicylic acid with the help of acetic anhydride .

As , the  acid anhydride is very sensitive to moisture , as it can hydrolyze into two molecules of  acids,

Hence , the reaction involving acid anhydride  are conducted in anhydrous solvents .

Hence ,

if water is  present in the glassware then , some of the acetic anhydride is wasted , Which in turns reduces the yield than that expected .
