Buffers in Education. II. Preparation and Use

D. Dabić and D. Petrin


The text discusses how to choose buffers depending on the purpose, and how to prepare them in several ways. With the necessary understanding of acid dissociation constants and buffer mechanisms, it is meant to give the readers the correct approach when preparing desired buffer solutions by taking into account all factors that may affect the buffer system. Therefore, the text covers important concepts, and links them with their applications in the world of science and engineering. It also explains buffer capacity and its role, as well as the concept of ionic strength and how it affects the pH. At the end, explanations of buffers are summarized and some numerical problems are given to enable self-evaluation of the comprehension of the given subject.
