WebWeak acids are acids that don't completely dissociate in solution. In other words, a weak acid is any acid that is not a strong acid. The strength of a weak acid depends on how much it dissociates: the more it dissociates, the stronger the acid. WebWhen dissolved in water, an equilibrium is established between the concentration of the weak acid and its constituent ions. Some common examples of weak acids are listed below. Formic acid (chemical formula: HCOOH) Acetic acid (chemical formula: CH 3 COOH) Benzoic acid (chemical formula: C 6 H 5 COOH) Oxalic acid (chemical formula: C 2 H 2 O 4)

WebJan 29, 2024 · Anne Marie Helmenstine, Ph.D. Updated on January 29, 2024. A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. The conjugate base of a weak acid is a weak base, while the conjugate acid of a weak base is a weak acid. WebIn contrast, acetic acid is a weak acid, and water is a weak base. Consequently, aqueous solutions of acetic acid contain mostly acetic acid molecules in equilibrium with a small concentration of \(H_3O^+\) and acetate ions, and the ionization equilibrium lies far to the left, as represented by these arrows:
