What is HC9H7O4?

What is HC9H7O4?

Aspirin | HC9H7O4 – PubChem.

What is the chemical reaction of aspirin?

The preparation consists of an esterification reaction catalyzed by acid (H2SO4 or H3PO4), where salicylic acid treated with acetic anhydride gives acetylsalicylic acid (aspirin). In this reaction, a hydroxyl group is converted to an ester, with acetic acid as a byproduct.

What is the conjugate base of HC9H7O4?

Acetylsalicylate
Acetylsalicylate is a benzoate that is the conjugate base of acetylsalicylic acid, arising from deprotonation of the carboxy group. It derives from a salicylate. It is a conjugate base of an acetylsalicylic acid….4.3Related Compounds.

What is the molar mass of HC9H7O4?

A tablet contains aspirin, HC9H7O4, (molar mass = 180.1 g/mol) which has one acidic hydrogen.

Which are the rotatable bonds in Aspirin?

Chemical Structure Description The aspirin molecule contains a total of 21 bond(s) There are 13 non-H bond(s), 8 multiple bond(s), 3 rotatable bond(s), 2 double bond(s), 6 aromatic bond(s), 1 six-membered ring(s), 1 carboxylic acid(s) (aromatic), 1 ester(s) (aliphatic) and 1 hydroxyl group(s).

What is the chemical equation for the synthesis of aspirin?

*The chemical equation corresponding to the synthesis reaction is: C7H6O3 + (CH3CO)2O → C9H804 + CH3COOH. Please use this balanced equation and the weight of salicylic acid used to calculate the theoretical yield.

Why is glycine added to aspirin?

Glycine is a natural amino acid which reduces the harmful effects of aspirin by preventing acid build-up and damage to stomach lining.

Is c9h7o4 an acid or base?

Acetylsalicylate is a benzoate that is the conjugate base of acetylsalicylic acid, arising from deprotonation of the carboxy group. It derives from a salicylate. It is a conjugate base of an acetylsalicylic acid….4.3Related Compounds.

Is c9h7o4 a weak base?

Since HC9H7O4, CH3COOH, and HNO2 are weak acids, thus these three are not a Bronsted-Lowry base.

Is aspirin polar or nonpolar?

Aspirin is a polar molecule with dipole-dipole attraction bonds and an -OH (hydroxyl) segment as part of a carboxylic acid group.

What is the pH of acetylsalicylic acid?

Aspirin (acetylsalicylic acid) has a pKa of 2.97 Calculate the percentage of aspirin (acetylsalicylic acid) available for absorption in the stomach (pH = 2.0) and in the duodenum at (pH = 4.5).
