What else can I help you with?
Suppose 5.0 g of salicylic acid is heated with an excess amount of acetic acid. What is the expected yield of acetylsalicylic acid?
This reaction will not proceed, as the equilibrium is far to the left. In order to synthesize acetylsalicylic acid, one must use acetic anhydrate, and the reaction forms acetic acid instead of water.
What is the balanced equation for the reaction between salicylic acid and acetic anhydride?
The balanced equation for the reaction between salicylic acid and acetic anhydride to form aspirin (acetylsalicylic acid) is: salicylic acid + acetic anhydride → aspirin + acetic acid.
Why is salicylic acid more acidic than acetylsalicylic acid?
Salicylic acid dissociates in water to form a carboxylic acid group, making it more acidic compared to acetylsalicylic acid which has an ester group that is less acidic. The presence of the -OH group in salicylic acid contributes to its higher acidity compared to the -OR group in acetylsalicylic acid.
What is the equation for the reaction of salicylic acid with Acetyl chloride and pyridine?
The reaction of salicylic acid with acetyl chloride and pyridine results in the formation of acetylsalicylic acid (aspirin). The general equation for this reaction is: salicylic acid + acetyl chloride → acetylsalicylic acid + hydrogen chloride
Simple explanation on how salicylic acid acetyl is made?
Salicylic acid acetyl is made by reacting salicylic acid with acetic anhydride in the presence of an acid catalyst, such as sulfuric acid, to form acetylsalicylic acid. This reaction causes the hydroxyl group (-OH) of salicylic acid to be acetylated, resulting in acetylsalicylic acid, commonly known as aspirin.

What is the chemical reaction between acetic anhydride and salicylic acid?
The chemical reaction between acetic anhydride and salicylic acid is called esterification. This reaction forms acetylsalicylic acid, which is commonly known as aspirin.
Is aspirin a strong acid?
Salicylic acid has a pKa of 1.96 and acetylsalicylic acid (Aspirin) has a pKa of 3.48. Therefore salicylic acid is the stronger acid.
Is aspirin a carboxylic acid and an ester?
Aspirin is acetylsalicylic acid and an acetate ester of salicylic acid.
Why acetylsalicylic acid is not a phenol group?
ASA (acetylsalicylic acid) or Aspirin is synthesised by reacting Salicylic Acid with Acetic Anhydride. During this esterification, the dehydration occurs on the hydroxyl group attached to the benzene ring. As a result, the product no longer possesses the Phenol functional group.
What is aspirin made out of?
Aspirin derives its name from its chemical formula, acetylsalicylic acid. The compound is formed from salicylic acid, which is derived from bark from a willow tree. The process was discovered to take away the intense stomach pains associated with salicylic acid.Interesting note: The same mechanism that makes salicylic acid into acetylsalicylic acid also turns morphene into heroin.
If 1.5g of salicylic acid is heated with an excess of acetic anhydride, what is the theoretical yield of acetylsalicyclic acid?
With 1,5 g of salicylic acid you can obtain theoretically 1,96 g aspirin (acetylsalicylic acid); but in the laboratory (or industry) I remember that the true yield of reaction is a little more than 90 %.
What is the relationship between salicylic acid and aspirin, and how do they differ in terms of their chemical composition and medicinal properties?
Salicylic acid is a precursor to aspirin, which is a derivative of salicylic acid. Aspirin is acetylsalicylic acid. They differ in their chemical composition as aspirin has an acetyl group attached to the salicylic acid molecule. In terms of medicinal properties, aspirin is commonly used as a pain reliever, anti-inflammatory, and fever reducer, while salicylic acid is often used in skincare products for its exfoliating properties.
