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.
In general, if Ka for the acid is larger than 1 x 10 -7, the buffer will be acidic. If Kb is larger than 1 x 10 -7, the buffer is basic. Buffer Capacity and pH Titration Curves. The most important property of a buffer is its ability to resist changes in pH when small quantities of acid or base are added to the solution.
