Where is the acetyl-salicylic acid compound formed?
The acetylsalicylic acid was hydrolizes in the small intestine to salicylic acid, which then was absorbed into de bloodstream
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.
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 %.
Why Salysilic acid is stronger than benzoic acid?
In salicylic acid the hydrogen atom in OH group have a tendency to form hydrogen bonding with oxygen atom in the COO - group thus leaving the H+ ion freely available. In case of ortho methoxy benzoic acid, the possibility of hydrogen bonding is avoided by the presence of strong -CH3 group. Hence salicylic acid is stronger than ortho methoxy benzoic 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.
Where is the acetyl-salicylic acid compound formed?
The acetylsalicylic acid was hydrolizes in the small intestine to salicylic acid, which then was absorbed into de bloodstream
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.
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.
What is the difference between old and new aspirin?
When aspirin gets old, it begins to decompose and you get a vinegar smell. If you smell that, the aspirin is decomposing and acetic acid is being released. Aspirin should be used before the decomposition occurs. It will still work, because the salicylic acid that does the work is still there. It can be corrosive to the stomach and that's why they combine it with a process that produces acetylsalicylic acid (aspirin). When decomposition occurs, you get salicylic acid and acetic acid.
Which from acetic acid or salicylic acid in aspirin is an alcohol?
Aspirin is a protected name belonging to Bayer A.G. (in some countries) for acetylsalicylic acid. Salicylic acid is a beta-hydroxy acid, meaning that it's both an acid and an alcohol. It serves as the alcohol in the esterification reaction.
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.

If you mix acetylsalicylic acid with baking soda what exactly happens?
When you mix salicylic acid with baking soda it produces a gas called carbon dioxide. This represents a chemical change.
What is the origin of Aspirin?
It was originally an extract of willow bark(containing salicylic acid). The formula is slightly different today though(acetylsalicylic acid, just an extra Acetyl group).
What is the chemical name for aspirin?
aspirin is a popularly known drug. the chemical name of aspirin is acetyl salicylic acid, an organic compound. it is prepared by the reaction of o-hydroxybenzoic acid(salicylic acid) with acetyl chloride or acetic anhydride.
Why Salysilic acid is stronger than benzoic acid?
In salicylic acid the hydrogen atom in OH group have a tendency to form hydrogen bonding with oxygen atom in the COO - group thus leaving the H+ ion freely available. In case of ortho methoxy benzoic acid, the possibility of hydrogen bonding is avoided by the presence of strong -CH3 group. Hence salicylic acid is stronger than ortho methoxy benzoic acid.
