As a technician in a large pharmaceutical research firm, you need to produce 100 mL of 1.00 M potassium phosphate solution of pH = 7.00. The pKa of H2PO4 is 7.21. You have 2.00 L of 1.00 M~ KH2PO4 solution and 1.50 L of 1.00 M~ K2HPO4 solution, as well as a carboy of pure distilled H2O. How much 1.00 M~ KH2PO4 will you need to make this solution?
