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. WebA base that can be dissolved in water is referred to as an alkali. When these substances chemically react with acids, they yield salts. Bases are known to turn red litmus blue. Acid Definition Chemistry. The terms acid and base have been defined in different ways, depending on the particular way of looking at the properties of acidity and basicity.
