Assay of Benzoic Acid

Molecular formula: C7H6O2 

Molecular Weight: 122.1 

Assay: Weigh accurately about 1.0 g and dissolve in 15 mL of warm ethanol (95%)  previously neutralized to phenolphthalein solution. Add 20 mL of water and titrate with 0.5 M  sodium hydroxide using phenolphthalein solution as an indicator.
