Arrhenius Acid-Base TheoryThe 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. Other ways of classifying substances as acids or bases are the Bronsted-Lowry concept and the Lewis concept.

Bronsted-Lowry Acid-Base ConceptThe Bronsted-Lowry theory classifies a substance as an acid if it acts as a proton donor, and as a base if it acts as a proton acceptor. Other ways of classifying substances as acids or bases are the Arrhenius concept and the Lewis concept.

Lewis Acid-Base ConceptThe Lewis theory classifies a substance as an acid if it acts as an electron-pair acceptor and as a base if it acts as an electron-pair donor. Other ways of classifying substances as acids or bases are the Arrhenius concept and the Bronsted-Lowry concept.
