Reference no: EM13540671

As a technician in a large pharmaceutical research firm, you need to produce 450.ml of 1.00M potassium phosphate buffer solution of pH = 7.13. The Pka of H2PO4 - is 7.21.

You have the following supplies: 2.00L of 1.00 M KH2PO4 stock solution, 1.50 L of 1.00 M KH2PO4 stock solution, and a carboy of pure distilled H20.

How much 1.00 M KH2PO4 will you need to make this solution?
