22. Buffer solutions are very important for many analytical applications. Which one of the following descriptions about buffer solutions is incorrect?
(A) Buffer solutions are generally from conjugate acid/base pairs.
(B) Buffer solutions can resist to changes of pH when the solutions are diluted or added with strong acids or bases.
(C) The buffer capacity is the measurement of ability that resists to pH changes.
(D) The buffer capacity of a solution is determined by the strength of the conjugate acid/base pair.
(E) The pH of a buffer solution can be determined by pH=pKa + log ([base]/[acid]).
