Best Answer: A solution has the greatest buffering capacity when the concentration of the weak acid is = at the concentration of its conjugate base. In this case i thing that the correct answer is c. Source(s): Dr.A Â· 6 years ago.
At very low p[H+] the [H+] term in the denominator predominates and buffer capacity rises exponentially with decreasing pH. The buffer capacity of a buffering agent is at a local maximum when p[H+] = pKa. It falls to 33% of the maximum value at p[H+] = pKa Â± 1 and to 10% at p[H+] = pKa Â± 1.5.
