Counterion of strong bases
WebFeb 3, 2024 · A neutralization reaction can be defined as the reaction of an acid and a base to produce a salt and water. That is, another cation, such as N a +, replaces the proton on the acid. An example is the reaction of CH 3 CO 2 H, a weak acid, with NaOH, a strong base: (16.7.1) CH 3 CO 2 H ( l) a c i d + NaOH ( s) b a s e H 2 O H 2 OCH 3 CO 2 Na ( … WebThe counterion of the anion exchanger usually is a weakly binding one–for example, Cl-–that can be replaced by anions with higher affinity, such as negatively charged amino acids on the protein surface. ...
