Question

11. The phosphate buffer system maintains an approximate pH of 6.8 in the intracellular fluid of all cells. This buffer system consists of dihydrogen phosphate ions (H2PO4-) and hydrogen phosphate ions (HPO42-). These two ions are in equilibrium with each other as indicated by the chemical equation below. H2PO4-(aq) + H2O(l) ? H3O+(aq) + HPO42-(aq) A. (4 pts) What is the ratio of HPO42- to H2PO4- at this pH?

Step 1

We need to find the ratio of hydrogen phosphate ions (\(HPO_4^{2-}\)) to dihydrogen phosphate ions (\(H_2PO_4^-\)) in a phosphate buffer system at a pH of 6.8. Show more…
