Carbon dioxide (CO2) is readily soluble in water, according to the equation CO2 + H20 2 H2CO3. Carbonic acid (H2CO3) is a weak acid. Respiring cells release CcO2 into the bloodstream. What will be the effect on pH of blood as that blood first comes in contact with respiring cells? A. Blood pH will decrease slightly. B. Blood pH will increase slightly. C. Blood pH will first increase, and then it decreases as CO2 combines with hemoglobin. D. Blood pH will first decrease, and then it increases sharply as CO2 combines with hemoglobin.
