Of the following solutions, which has the greatest buffering capacity? of the following solutions, which has the greatest buffering capacity? 0.221 m hf and 0.105 m naf 0.441 m hf and 0.209 m naf 0.882 m hf and 0.418 m naf 0.146 m hf and 6.90×10−2 m naf they are all buffer solutions and would all have the same capacity.

 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.

The best option is the 0.882 M HF and 0.418 M, because both molecules have higher concentrations than other options, that means,  this Buffer solution will last longer because it has more moles to be consumed when adding an acid or a base.
