Aphosphate buffer is involved in the formation of urine. the developing urine contains h2po4 and hpo42- in the same concentration as present in blood plasma. identify the acid and its conjugate base. write the ionization equation and the ka expression. 6.2 x 10^(8) a. the ka of h2po4 is 6.2 x 108. what is the pka? is this acid weaker or stronger than h2co3? which buffer system is more optimal for regulating ph in the body? b. using lechatlier's principle, what happens if the urine is acidified (h+ ions added)?
