Recall that an ideal buffer pairs are usually:
Weak acid + its conjugate base
Weak base+ its conjugate acid
High concentrated WA + Strong base
High concentrated WB + Strong acid
Of the following solutions, which has the greatest buffering capacity?
a. 0.296 M HF and 0.122 M NaF
b. 0.195 M HF and 8.02 x 10−2 M NaF
c. 0.591 M HF and 0.243 M NaF
d. 1.18 M HF and 0.486 M NaF
e. They are all buffer solutions and would all have the same capacity.
