You have at your lab bench the following chemicals: NaH2PO4(s), Na2HPO4(s), Na3PO4(s), NH4Cl(s), NaCH3COO(s), CH3COOH(l), 1.00 M NH3, 1.00 M NaOH, 1.00 M HCl, and deionized water. You also have standard glassware available.

a.) Describe how you would make 1 L of buffer with a pH of 5.00 using only pure materials and deionized water so that the total concentration of the conjugate acid/base pair is 0.200 M. Give the amounts of the pure materials in grams if they are solid or mL if they are liquid.

b.) Describe how you would make 1 L of buffer with a pH of 5.00 using only one of the pure materials and one of the 1.00 M solutions (HCl or NaOH) so that the total concentration of the conjugate acid/base pair is 0.200 M. Give the amounts of the pure materials in grams if they are solid or mL if they are liquid and the volume of solution in mL.
