Reference no: EM13704942

Problem- In a solution of 243 mM sodium phosphate buffer (so the concentration represents all forms of phosphate no matter the ionization state) at pH 7.2, what is the ratio of HPO4-2 to H2PO4- ? The pKa's of phosporic acid are 2.15, 6.86 and 12.32. The answer is unitless but reports your answer to the nearest 0.01.
