1. Arrhenius definition. : An acid is a substance that dissociates in water to produce H+ ions (protons), and a base is a substance that dissociates in water to produce OHâions (hydroxide); an acid-base reaction involves the reaction of a proton with the hydroxide ion to form water. 2.
The Arrhenius definition defines acids as substances which increase the concentration of hydrogen ions (H +), or more accurately, hydronium ions (H 3 O +), when dissolved in water. The Broensted-BrÃ¸nsted lowry definition is an: expansion an acid is a substance which can act as a proton. donorhe Arrhenius definition defines acids as substances which increase the concentration of hydrogen ions (H +), or more accurately, hydronium ions (H 3 O +), when dissolved in water.
