Salicylic acid is more polar than aspirin because it has a higher solubility in water due to the presence of a hydroxyl group that enhances its polarity. Aspirin, on the other hand, has an ester functional group, which reduces its overall polarity compared to salicylic acid.

Why salicylate is more soluble than salicylic acid?
Salicylate is more soluble than salicylic acid because salicylate is an ionized form of salicylic acid that can interact with water molecules through polar interactions, increasing its solubility in water. Salicylic acid, in its non-ionized form, has fewer interactions with water molecules, decreasing its solubility.
Is aspirin the strongest acid?
No, aspirin is not an acid in terms of acidity strength. Aspirin is a weak acid called acetylsalicylic acid. Strong acids like hydrochloric acid have a much lower pH and can fully dissociate in solution.
Why does aspirin dissolve in water?
Aspirin is a polar molecule due to the presence of functional groups like carboxyl and phenyl groups. Water is also a polar molecule. The interactions between the polar molecules of aspirin and water lead to the dissolution of aspirin in water through hydrogen bonding and other intermolecular forces.
How does aspirin dissolve in carbohydrate solution?
Aspirin is a weak acid that can dissolve in water due to its polar structure and hydrogen bonding. When aspirin is added to a carbohydrate solution, it can form hydrogen bonds with the hydroxyl groups of the carbohydrate molecules, helping it dissolve more readily in the solution.
Why acylation occur at phenol rather than carboxylic acid in salicylic acid?
Acylation occurs at the phenol group in salicylic acid due to the higher reactivity of the phenol hydroxyl group compared to the carboxylic acid group. The phenol group is more nucleophilic and readily reacts with acetyl chloride to form acetylsalicylic acid (aspirin). Additionally, the carboxylic acid group can interfere with the reaction due to its ability to form hydrogen bonds, making it less reactive towards acylation.
What is more polar methyl salicylate or salicylic acid?
salicylic acid (an acid) is more polar than methyl salicylate (an ester)
Do we still harvest aspirin from a willow tree?
,,,plants have small amount of salicylic acid,,,but the willow tree have more salicylic to be used in making an aspirin,,,researchers said that willow tree is the only tree having more salicylic acid

What causes water to taste like aspirin?
Aspirin tastes a little bit like vinegar and the older the aspirin is, the more it tastes like vinegar. This is because vinegar is a solution of acetic acid and aspirin is made from acetic acid and salicylic acid.
Is salicylic acid dissolved in HCl?
Salicylic acid does not dissolve well in hydrochloric acid (HCl). Salicylic acid is more soluble in organic solvents like ethanol or acetone.
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.
If 1.5g of salicylic acid is heated with an excess of acetic anhydride, what is the theoretical yield of acetylsalicyclic acid?
The molar mass of salicylic acid is 138.12 g/mol. To convert 1.5g to moles: 1.5g / 138.12 g/mol = 0.0109 mol. Since acetylsalicylic acid is formed by the reaction, the theoretical yield would be equal to the moles of salicylic acid used in the reaction. Therefore, the theoretical yield is 0.0109 mol of acetylsalicylic acid.
What are the Rf values for pure aspirin and salicylic acid With workings shown so i can understand thank you?
The Retardation Factor (RF) value of aspirin is 0.56. The RF value of salicyclic acid is 0.654. Although workings cannot be shown here, a more detailed explanation can be found on the RSC website.
What is acetylsalicylic acid more commonly known as?
Aspirin is the more common name for acetylsalicylic acid.
How does the structure of salicylic acid differ from that of benzoic acid?
Salicylic acid has a hydroxyl group (-OH) attached to the benzene ring, while benzoic acid has a carboxylic acid group (-COOH) attached to the benzene ring. This difference results in salicylic acid being a phenol derivative and having different chemical properties compared to benzoic acid.
Which one is more polar pure aspirin or crude aspirin?
Medicinal asperin is synthesised.
