75. Salicylic acid, HOC6H4CO2H, and its derivatives have been used as pain relievers for a long time. Salicylic acid occurs in small amounts in the leaves, bark, and roots of some vegetation (most notably historically in the bark of the willow tree). Extracts of these plants have been used as medications for centuries. The acid was first isolated in the laboratory in 1838. (a) Both functional groups of salicylic acid ionize in water, with Ka = 1.0 × 10−3 for...

Question: In the general chemistry lab, students synthesize
aspirin from salicylic acid and acetic anhydride. In the lab,
students use sulfuric acid as a catalyst, but I want to consider an
alternate method for synthesizing aspirin using sodium acetate as a
catalyst:
a. Draw the structure of sodium acetate. Is sodium acetate a
stronger or weaker base than sodium hydroxide (NaOH). Explain. (1.5
pts)
b. Consider the structure of salicylic acid. It contains two

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...
