10) A student prepares aspirin (acetylsalicylic acid, C,H,0.) by reacting salicylic acid (C,H,O,) with acetic anhydride (C.H.O.). The balanced equation for the reaction is: 2 C,H,O, + C,H,O, + 2 C,H,O, + H,O The lab calls for 3.00 g of salicylic acid to be mixed with 6.40 g of acetic anhydride. What is the limiting reagent and what is the maximum amount of aspirin which can be prepared if the yield for the reaction is 91%?

10) A student prepares aspirin (acetylsalicylic acid, C,H,0.) by reacting salicylic acid (C,H,O,) with acetic anhydride (C.H.O.). The balanced equation for the reaction is: 2 C,H,O, + C,H,O, + 2 C,H,O, + H,O The lab calls for 3.00 g of salicylic acid to be mixed with 6.40 g of acetic anhydride. What is the limiting reagent and what is the maximum amount of aspirin which can be prepared if the yield for the reaction is 91%?
Draw the product of the reaction of salicylic acid with (a) one of NaOH. (b) two equivalents of NaOH, and (c) two equivalents of NaHCO_3.
