You can simplify the calculation if you make 1 liter of buffer. Exercise 7. 100 mL phosphate buffer solution with 0 M concentration at pH 8 and pH 12 were prepared. Select the pKa value that is closest to the pH of your buffer. Choose a buffer with an effective pH range for your specific assay. 45 by an important buffer system made of carbonic acid and the bicarbonate anion. e. Buffer Capacity and Ionic Strength: The molar strength of the two components of the buffer should be chosen to give adequate buffering capacity. To 900 ml of a 4 g/l solution of sodium dihydrogen phosphate R, add 100 ml of a 2. Even a slight change in pH can result in metabolic acidosis or alkalosis, resulting in severe metabolic complica-tions.
