Buffer capacity is an important concept in analytical chemistry. Conventional calculations often neglect volume changes that occurs when a buffer solution mixes with a sample solution, yielding what is termed "static" buffer capacity. In practical applications, however, the volume of the buffer solution mixed with the sample solution is often substantially greater than the original volume of the buffer solution, therefore necessitating the consideration of "dynamic" buffer capacity in textbook. This paper proposes a "de-formulized" strategy for addressing "dynamic" buffer capacity problem, which is completely based on the underlying logic of the discipline. This approach avoids adding to the memorization burden of students' learning.
