Draw an expanded Lewis Structure for Salicin, Salicylic acid, and aspirin
Propose a structure for the polymer formed by intermolecular reaction of salicylic acid during the synthesis of aspirin. Which is the stronger acid, aspirin or salicylic acid?
A sample of crude aspirin containing 20.0% salicylic acid is neutralized with NaOH. The structure for aspirin and salicylic acid are shown below. What volume of 0.150 M NaOH would be required to neutralize 560 mg of this sample of crude aspirin? a) 25.8 mL b) 15.2 mL c) 20.7 mL d) 22.0 mL e) none of these
Mass of salicylic acid recovered= 11.495g Used 1.410g of salicylic acid when synthesizing aspirin. Mass of acetylsalicylic acid(aspirin) recovered= 2.365g Discuss your yields, % yield of salicylic acid and aspirin. The reaction is the synthesis of salicylic acid from oil wintergreen, and then using the salicylic acid to synthesize aspirin. THANK YOU IN ADVANCE

Mustrates treat all types of ilnesses. Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the andient Greeks as a treatment for pain and fever. Salicylic acid (and many related phenols) are very hard on your Ho stomach, but when esterified, as aspirin is, they are much better tolerated. Simple esters are...
When aspirin is hydrolyzed, what are the products? a.) salicylic acid and ethanol b.) salicylic acid and ethanal c.) salicylic acid and ethanoic acid d.) ethanol and acetic acid
2. Draw the structure of aspirin. Circle and label the ester group and the carboxylic acid group. What functional group of the aspirin causes it to irritate the stomach? 3. In the synthesis of aspirin what is the function of the H2so4? 4. If the melting point of the aspirin you synthesize has a wide melting point range, what does that indicate? 5. If you treat your synthesized aspirin with FeClh and you get a purple color, what does that...
When old aspirin breaks down salicylic acid is formed. What functional group does salicylic acid have that aspirin does not? -OH Opera Olaondo acid catalyst + some stuff -©—OH 0-C-CH3 + CH3—C—OH acetic acid OH aspirin Salicylic acid
In the lab calledd Synthesis of Aspirin, the mass of salicylic acid is 3.037g , the mass of dried Aspirin finally is 2.793. What is the moles of salicylic acid used? What is the moles of aspirin expected? What is the mass of aspirin expected?
Organic chemistry -Carboxylic acid homework
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
potentially...
