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.
Buffer mixtures maintain their buffer action only if limited amounts of an acid or an alkali are added. In other words,every buffer mixture has well-defined buffer capacity. This capacity is maximum when the solution contains equivalents amounts of the weak acid and its salt or weak base and its salt, that is,when the ratio of salt to acid or salt to base is unity.
