Buffer Capacity Buffer Capacity of a solution is defined as the number of moles of a strong acid or a strong base that causes 1.00 liter of the buffer to undergo a 1.00-unit change in pH. Mathematically, the buffer capacity is given by: Buffer capacity = β = dc b /dpH = - dc a /dpH

Unformatted text preview: where dc b is the number of moles per liter of strong base and dc a is the number of moles per liter of strong acid added to the buffer. Since adding strong acid to a buffer causes the pH to decrease, dc a /dpH is negative and buffer capacity is always positive....
