question 4 & 5
Question 4 (2 points) if you accidently read the procedure wrong while doing the synthesis of aspirin and mixed Sg of salicylic acid with 2 mL of acetic anhydride (instead of correctly mixing 2g of salicylic acid with 5 mL of acetic anhydride), what would be the effect7(density of acetic anhydride = 1.082 g/mL) a Nothing, it would still work just fine Ob Reaction would work fine, but less product would form since acetic anhydride is...
