News Popular Imported From Safari Challenge Problem #6 The pH of human blood needs to be between 7.35 and 7.45. You want to prepare a buffer solution that gives a pH of 7.40. You decide to use a sodium phosphate buffer: the acid is H2PO1 and the conjugate base is HPO You want the concentration of the acid to be 0.0100 M. 1. If the initial H2PO4 concentration is 0.0100 M, what is the initial concentration of HPO1 that will give a pH of 7.40? 2. What is the maximum molarity of acid that this buffer can neutralize without the pH dropping below 7.35? 3. What is the maximum molarity of base that this buffer can neutralize without the pH going above 7.45?
