Solution

As defined by Arrhenius: An Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H⁺). An Arrhenius base is a substance that dissociates in water to form hydroxide (OH^–) ions.

But all acids do not necessarily dissociates in water to form hydrogen ions (H⁺). for example Boric acid; As H3B03 is basically B(OH)3 and therefore it cannot give H+ ions.

Like this all base do not necessarily dissociates in water to form hydrogen ions (H⁺).for example Ammonia.ammonia does NOT contain hydroxide ions, i.e. its chemical formula is NH3, it does not fall under the Arrhenius' umbrella.
