Acids on the other hand would contribute #H^+# ions when dissociated. The easiest way to identify Arrhenius bases is to identify #OH^-# in a compound formula.
Arrhenius argued that bases are neutral compounds that either dissociate or ionize in water to give OH-ions and a positive ion. NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH -) and sodium (Na +) ions.l(OH) 3, for example, acts as an acid when it reacts with a base. Conversely, it acts as a base when it reacts with an acid. The Br nsted Definition of Acids and Bases. The Brnsted, or Brnsted-Lowry, model is based on a simple assumption: Acids donate H ions to another ion or molecule, which acts as a base.
