Why Carboxylic Acids Are More Acidic

Carboxylic acids are the strongest organic acids, but they are still much weaker than mineral acids such as HCl. In water, they ionize by losing the hydroxyl proton. This forms a carboxylate ion, which is stabilized by resonance.

The strength of this ionization is shown by the acid dissociation c...

Carboxylic acids exhibit significant acidity in the presence of bases, forming carboxylate anions.

The pK_a values of most carboxylic acids—ranging from 4-5—are much lower compared to other compounds such as alcohols, that have pK_a values around 16-18.

The lower pK_a or high...
