One of the buffer systems the human body has to regulate pH is based on the phosphate anion. If blood has a pH of 7.40, and the three Ka values for phosphoric acid are 7.52 × 10−3, 6.23 × 10−8, and 4.8 × 10−13, write the chemical equilibrium equation showing the phosphate species that are involved in this buffer
