WebThe buffering capacity is the amount of strong acid or base that can be added to the buffer before the buffer can no longer resists changes in pH. Quantitatively, it is often defined as the number of moles of strong acid or base required to change the pH of 1 liter of the buffer solution by 1 pH unit. We will determine the buffer capacity by determining the number … http://clymer.altervista.org/buffers/cit.html
