Which solution has the best buffering capacity?
WebOct 22, 2024 · Answer: The buffer solution with best buffering capacity is the 0.882 M HF and 0.418 M Explanation: A buffer solution works best when having equal amount of both molecules. The buffer capacity will last until the last mol of the conjugate acid (HF) or the conjugate base (F) is consumed, and then, the pH will change significantly.
