WebJan 30, 2024 · In chemistry, acids and bases have been defined differently by three sets of theories. One is the Arrhenius definition, which revolves around the idea that acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (H +) ions while bases produce hydroxide (OH -) ions in solution. WebIn an operational sense, an acid is any substance that increases the concentration of the H + ion when it dissolves in water. A base is any substance that increases the concentration of the OH - ion when it dissolves in water. These definitions tie the theory of acids and bases to a simple laboratory test for acids and bases.
The word "base" came into use in 1717 by French chemist Louis Lémery. Lémery used the word as a synonym for Paracelsus' alchemical concept of a "matrix" in alchemy.
