WebBy analogy, a strong base is a compound that is essentially 100% ionized in aqueous solution. As with acids, there are only a few strong bases, which are also listed in Table 12.4.1. If an acid is not listed in Table 12.4.1, it is likely a weak acid, which is a compound that is not 100% ionized in aqueous solution. WebNote that depending on your class—or textbook or teacher—non-hydroxide-containing bases may or may not be classified as Arrhenius bases. Some textbooks define an Arrhenius base more narrowly: a substance that increases the concentration of OH − …
