Is salicylic acid an appropriate compound to use for calibration curve for acetylsalicylic acid? Why or why not?
The calibration curve for acetyl salicylic acid is constructed from standard solutions prepared from pure salicylic acid. Therefore, salicylic acid can be used as an appropriate compound for the calibration curve of acetyl salicylic acid.

Why is it possible to use salicylic acid solutions to construct the standard graph for measuring the unknown acetylsalicylic acid (Aspirin)? Select one: O a. Salicylic acid and acetylsalicylic acid are both converted to the same product, which is measured in the spectrophotometer. O b. Salicylic acid and acetylsalicylic acid have similar properties as pain relievers, so can be directly compared. O c. Salicylic acid and acetylsalicylic acid are two different names for the same compound Od. Salicylic acid is...
Explain the differences in the stretches of the C=O in salicylic acid and in acetylsalicylic acid. I found stretches of about 1650 for salicylic acid and 1680 for acetylsalicylic acid. Is it correct for the carboxylic acid C=O stretch to be greater for acetylsalicylic acid? If so, what would cause this? Conjugation/Resonance possibly?

3. Calculate the theoretical yield of acetylsalicylic acid from 2.20 g of salicylic acid assuming the salicylic acid is the limiting reactant. [3] 4. Assume that 1.65 g of acetylsalicylic acid is produced from the reaction above. Calculate the percent yield. [2]
Experiment 2: Synthesis of Aspirin (Acetylsalicylic Acid ) 1. How many moles of salicylic acid are there in 1.0 grams of salicylic acid? 2. How many moles of acetic anhydride are there in 3 mL of acetic anhydride? 3. When 1.0g of salicylic acid and 3 mL of acetic anhydride react, DETERMINE which one is the limiting reactant (you can go to General Chemistry if you need help about limiting reagent)? 4. What is phosphoric acid used for in the...
Aspirin (acetylsalicylic acid) may be formed from salicylic acid and acetic acid as follows: 13a How many g of aspirin may be produced from 6.94 × 102 mol salicylic acid
calculate the theoretical yield of acetylsalicylic acid if 2.50g salicylic acid is allowed to react with 2.00g of acetyl chloride in excess pyridine.
19. Salicylic acid, CeH,OHCOOH, is used in the manufacture of acetylsalicylic acid (aspirin) and methyl salicylate (wintergreen flavor). A saturated solution of salicylic acid contains 2.2 g of the acid per liter of solution and has a pH of 2.43. What is the value of Ka for salicylic acid?
H3PO4 OH + OH OH salicylic acid acetic anhydride acetic acid acetylsalicylic acid (aspirin) 1. Why is it better to perform acetylation with acetic anhydride rather than using a Fischer esterification with acetic acid? 2. Draw a complete arrow-pushing mechanism for the reaction. 3. When an old sample of aspirin is left in moist conditions, it will begin to smell like vinegar. Draw a reaction scheme and briefly explain what happened.
In this lab you are synthesizing acetylsalicylic acid (ASA) from salicylic acid using acetic anhydride, with phosphoric acid as a catalyst. If the amount of salicylic acid at the start of the reaction was 1.05 g, what is the theoretical yield of ASA in g? Assume acetic anhydride is in excess.
