Which of the following is true about buffers such as HEPES, TRIS, and MOPS? A) The Henderson-Hasselbalch equation applies to them. B) They consist of simple weak acids and bases. C) They are less resistant to changes in temperature than are other buffers. D) We can use them interchangeably because they all have the same pK_a.

Question

Quizplus · Accepted Answer

Buffers like HEPES, TRIS, and MOPS are indeed governed by the Henderson-Hasselbalch equation, which describes the relationship between the pH of a solution and the pKa (acid dissociation constant) of the acid in the buffer system. This equation is fundamental to understanding how buffers work to maintain pH levels in solutions.
