Quizplus · Accepted Answer

All of these factors are important when deciding if a buffer will be effective for an experiment. The pK's of the buffer can help determine the pH range over which the buffer will be effective. The buffer capacity is important because it determines how much acid or base can be added to the buffer before the pH changes significantly. The concentration of the buffer is important because a lower concentration may not provide enough buffering capacity for the experiment. And determining whether the experiment is likely to generate hydrogen ions or hydroxide ions is important to ensure that the buffer can effectively neutralize these ions and maintain a stable pH.
