There is a buffer system (H2PO4-- HPO42-) in blood that helps keep the pH at about 7.40. (Ka H2PO4-=6.2 x10-8).
A) Calculate the [H2PO4-]/[HPO42-] ration at the normal pH of blood. (Answer - 0.64)
B) What percentage of the HPO42- ions are converted to H2PO4- when the pH goes down to 6.80. (Answer - 54%)
C) What percentage of the H2PO4- ions are converted to HPO42- when the pH goes up to 7.80. (Answer - 47%)
