WebFormula to calculate buffer capacity. ∆n is the equivalents of strong base or acid added per volume liter. ∆pH is the change in pH. Example: Calculate the buffer capacity if you add 0.080 mole of HCl to 100ml phosphate buffer and the pH drops exactly one unit . Therefore, the buffer capacity is 0.80. Share. Tweet. Reddit.
