If hydronium ions are produced with dissolved in water, a substance classifies as an acid. If conversely hydroxide ions are produced, Arrhenius classifies the substance as a base. Examples of Arrhenius acids are HCl, H2SO4, and HBr. Arrhenius base examples would be NaOH, KOH, and Mg(OH)...

TheArrheniusdefinition[75]of acid-base reactions is a development of the hydrogen theory of acids, devised by Svante Arrhenius, whose work was used to provide a modern definition of acids and bases that followed from his work in 1884 with Friedrich Wilhelm Ostwald in establishing the presence of...

The Romans refined this concept, calling sour-tasting substances like vinegar and lemon juice "acere," from which the modern word acid is derived. Defining a base was more elusive, but most societies understood the practical application of making a base, soap, from the reaction of ash and ...
3. equally balanced state; equilibrium. 4. an expression or a proposition, often algebraic, asserting the equality of two quantities. 5. a symbolic representation in chemistry showing the kind and amount of the starting materials and products of a reaction. [1350–1400; Middle English < La...
an acid forms its conjugate base. Gain of a proton by a base forms its conjugate acid. A double reaction arrow is used between starting materials and products to indicate that the reaction can proceed in the forward and reverse directions. These are equilibrium arrows. Examples: Acids and ...
