CHEM 162 – LAB EXPERIMENT 6 - SYNTHESIS OF ASPIRIN PRACTICE EXAM TEST SOLUTION 2022
acetylsalicylic acid - active ingredient in aspirin



Stirring - __ ensures consistent temperatures and concentrations of reagents throughout the solution. It
also enhances the probability of chemicals colliding.



Dilution - Changing the concentration of the solution



Reflux - Heating the reaction to the boiling point of the solution



low temperature - Cooling the temperature to slow the rate of reaction



Anhydrous conditions - Running the reaction under air-free conditions



Running the reaction - Stirring, dilution, reflux, low temp., and anhydrous conditions are all techniques
that can be used in



Quenching, extraction, drying, filtration, condensing - 5 techniques used to stop the reaction and begin to
isolate the product



Quenching - Stopping the reaction by quenching the reagents before product can be isolated



Extraction - Separating the material of interest away from some of the other chemicals in the crude
reaction mixture



Drying - Separating your product from excess water



Filtration - Removing your product (if a solid) or a different solid impurity from the liquid solution



Condensing - Removing solvent from the solution to leave only product behind
