Design a buffer that has a pH of 8.25 using oneof the weak base/conjugate acid systems shown below.
| Weak Base | Kb | Conjugate Acid | Ka | pKa |
|---|
CH3NH2 | 4.2×10-4 | CH3NH3+ | 2.4×10-11 | 10.62 |
C6H15O3N | 5.9×10-7 | C6H15O3NH+ | 1.7×10-8 | 7.77 |
C5H5N | 1.5×10-9 | C5H5NH+ | 6.7×10-6 | 5.17 |
How many grams of the chloride salt of theconjugate acid must be combined with how many grams of the weakbase, to produce 1.00 L of a buffer that is1.00 M in the weak base?
grams chloride salt of conjugate acid =
grams weak base =
