Web12 de set. de 2024 · Buffer capacity depends on the amounts of the weak acid and its conjugate base that are in a buffer mixture. For example, 1 L of a solution that is 1.0 M in acetic acid and 1.0 M in sodium acetate has a greater buffer capacity than 1 L of a solution that is 0.10 M in acetic acid and 0.10 M in sodium acetate even though both solutions … WebFrom a table of molar masses, such as a periodic table, we can calculate the molar mass of NaF to be equal to 41.99 g/mol. HF is a weak acid with a K a = 6.6 x 10 -4 and the concentration of HF is given above as 1 M. Using this information, we can calculate the amount of F - we need to add. The dissociation reaction is:
