How Do We Measure the Strength of an Acid or Base

Strong acid An acid that is completely ionized in aqueous solution. [Pg.46]

Weak base A base that only partially ionizes in aqueous solution. [Pg.46]

A strong acid or strong base is one that ionizes completely in aqueous solution. When HCl is dissolved in water, a proton is transferred completely from HCl to HgO to form Cl and H3O. There is no tendency for the reverse reaction to occur—for the transfer of a proton from to Cl to form HCl and HgO. Therefore, when we [Pg.46]
