Procedure

Citric acid monohydrate (Mwt 211 g/mole) was prepared in deionised water at a concentration of 0.1 M. A solution of tri-sodium citrate dihydrate, 0.1 M, (Mwt 294.1 g/mole) was also prepared in deionised water. Citrate buffer solution pH 3 was prepared by mixing 40% v/v citric acid monohydrate solution (0.1 M), 10% v/v trisodium citrate dihydrate solution (0.1 M) and 50% v/v deionised water and the final pH was measured using a pH Meter (3320 JENWAY).
