Definition of a weak base
WebA strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca (OH) 2, respectively. WebFeb 2, 2024 · The larger the Kb, the stronger the base and the higher the OH − concentration at equilibrium. The values of Kb for a number of common weak bases are …
