1. What would happen if water was present in the initial reaction mixture? What chemical impact would this have on the acetic anhydride starting material? What chemical impact would this have on the acetylsalicylic acid forming in solution? Draw balanced chemical equations for these two potential side reactions: 2. Explain in detail how phosphoric acid catalyzes the acetylation of salicylic acid? Use structure to illustrate our point
write the balanced chemical equation and corresponding equilibrium expression for the each step in the ionization of phosphoric acid ( apolyprotic acid ) in water?
