a) How would you prepare a 250 ml solution, 0.5 M in sodium phosphate buffer at pH of 7.0. You have in the laboratory monobasic sodium phosphate (NaH2PO4) and diabasic sodium phosphate (Na2HPO4). pKa = 7.2
b) Describe how you would prepare the above buffer solution if you only had NaH2PO4, and a solution of NaOH. What other equipment would you need?
