9. Based on your work with benzoic acid, show the reaction between salicylic acid and potassium hydroxide. Label the acid, base, conjugate acid and conjugate base.

Salicylic Acid:

Salicylic Acid is an hydroxy acid that is found as a natural compound in plants. It's IUPAC name is 2-hydroxybenzoic acid. Salicylic acid has an odorless white to light tan solid color. It sinks and mixes very slow with water.
