Procedure

Reagent(ii) is a buffer prepared by first dissolving 144.8 grams (1.020 mol) of disodium hydrogen phosphate in 1.00 liter hot deionized water. The phosphate dissolved in the hot deionized water upon stirring. To this solution 102.95 grams (0.4902 mol) of citric acid monohydrate were added. The resulting solution was then diluted to 10.0 liters with additional deionized water, thus forming a citrate-phosphate solution, with a pH of 5.0.
