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 Acid-Base Theory. The Arrhenius acid-base concept classifies a substance as an acid if it produces hydrogen ions H(+) or hydronium ions in water. A substance is classified as a base if it produces hydroxide ions OH(-) in water. This way of defining acids and bases works well for aqueous solutions, but acid and base properties are observed in other settings.
