The h2PO4- / hpo4 2- buffer is important in human physiology. The pKa for H2PO4- is 7.21.
The pH of urine is measured to be 5.45 and its total phosphate content (H2PO4- + HPO4 2-) is 48.8mmol L-1. Calculate the concentration of each phosphate species present in the sample.
We've been working on this for ages and are totally stuck.
