QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...

Aspirin is acetylsalicylic
acid (ASA) (
C9H8O4). It reacts with NaOH ( a
base) to produce salt (sodium acetylate) and water. Both Aspirin
and NaOH react in 1:1 molar ratio, as
C9H8O4
+
NaOH →
NaC9H7O4
+ H2O
So, moles of NaOH = moles of ASA
Or, mmol of of NaOH = mmole of
