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.
They are made up of a conjugate acid-base pair such as HC 2 H 3 O 2 /C 2 H 3 O 2-or NH 4 + /NH 3. They work because the acidic species neutralize the OH-ions while the basic species neutralize the H + ions. The buffer capacity is the amount of acid or base the buffer can neutralize before the pH begins to change to a significant degree. This depends on the amount of acid or base in the buffer.
