An unsuspecting individual had 4.40 mL of 1.000 M HCl injected into their bloodstream. Assuming that the person has 1 gallon of blood circulating, and that the buffering capacity is controlled by phosphate buffer present at a formal concentration of 0.0250 moles L?1 and pH of 7.35, what is the global pH change incurred after injection of the HCl? What would the pH change be if this same amount of 1.000 M HCl were put into a gallon of pure water?
