What is the pKa of carboxylic acid?

By Forinfos - 26/07/2025 - 0 comments

Several carboxylic acids exist with different pKa values. The simplest carboxylic acid, acetic acid, has a pKa value of 4.7. A carboxylic acid is an organic compound containing the functional group COOH. Additional carboxylic acids include benzoic and formic, with pKa values of 4.2 and 3.7, respectively.

Because they are proton donors, carboxylic acids are considered Bronsted-Lowry acids. They are weak acids and partially dissociate into H+ cations and RCOO - anions in neutral aqueous solution. Carboxylic acids can be prepared by the oxidation of arene side-chains, the oxidation of primary alcohols, the oxidation of aldehydes and the oxidative cleavage of alkenes and alkynes.
