You have been asked to prepare 250 mL of a buffer solution that can maintain a pH of 5.05 at room temperature. You have been provided with two solutions, aqueous citric acid (1 M) and aqueous sodium citrate (0.1 M). Calculate the volumes (in mL) of the citric acid solution (VA) and the sodium citrate solution (Va) that should be combined to make the requested buffer solution. [1.5 marks each] pk.(citric acid) = 5.40 VA= V = 11 mL. Give your volume to 1 d.p. mL. Give your volume to 1 d.p.
