Ionization of Acids and Bases - Department of Chemistry

WebAn acid or base's strength refers to its degree of ionization. A strong acid will completely ionize in water while a weak acid will only partially ionize. Since there are different degrees of ionization, there are different levels of weakness. Fortunately, there is a simple quantitative way of expressing this. WebA concentrated buffer can neutralize more added acid or base than a dilute buffer. A more concentrated buffer will have a higher buffer capacity than one which is more dilute. Effectiveness of Buffers. A buffer will be most effective when the [base]:[acid] = 1 equal concentrations of acid and base. A buffer will be effective when; 0 < [base ...
