Types of Bases Bases may be categorized according to their degree of dissociation in water and reactivity. Astrong basecompletely dissociates into its ions in water or is a compound that can remove a proton (H+) from a very weak acid. Examples of strong bases include sodium hydroxide (NaOH...
pKa is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger acid. That is, the lower value indicates the acid more fully dissociates in water. pKa and Buffer Capacity In addition to using pKa to gauge the strength of an acid, it may be...
