A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. It has the property that the pH of the solution changes ...

name Janelle Y. status student age 18 Question - Hi there Titration Curves - ph and Buffers Why the pH of a buffer is independent of the buffer concentration, but the buffer capacity does depend on the concentration?

Another thread on this topic recently (may have been in another chem forum), and the conclusion was that there is no generally accepted quantitative definition of buffer capacity. So if someone asked you this, the first step is to find out how they define buffer capacity.

Alkalinity is simply the water's ability to maintain its pH (from dropping and to an extent rising). In other words it is a mesaure of the water's buffer capacity.

Buffer capacity refers to the amount of acid or base that can be added to a buffer solution before its pH changes. A symmetrical buffer can demonstrate that the most effective buffer exists when the concentrations of both the weak acid and it’s salt are high and are equal to each other.
