Benzoic acid is a weak acid that has antimicrobial properties. Its sodium salt, sodium benzoate, is a preservative found in foods, medications, and personal hygiene products. Benzoic acid dissociates in water:
C6H6COOH<-->C6H5COO + H

The pKa of this reaction is 4.2. In a 0.52 solution of benzoic acid, what percentage of the molecules are ionized?

-
1.1%

JUST DID THIS ON MASTERING CHEMISTRY! GOOD LUCK
