You are asked to prepare a phosphate solution
1)which of the following compounds would you mix to make a bufferwith a pH of 8.0
2) (H3PO4, NaH2PO4, Na2HPO4, and Na3PO4). Hint phosphoric acid is atriprotic acid having pKa1 = 2.148, pKa2 = 7.199, and pKa3 =12.149.
3) If you want to prepare 500.0 mL of the buffer solution with atotal phosphate concentration of 0.200M, how many grams of each ofthe two selected compounds would you mix
