One of the Buffers That Contribute to PH Stability in Human

question 1

Multiple Choice

One of the buffers that contribute to pH stability in human blood is carbonic acid H₂CO₃. Carbonic acid is a weak acid that when placed in an aqueous solution dissociates into a bicarbonate ion (HCO₃⁻) and a hydrogen ion (H⁺) . Thus, H₂CO₃ ↔ HCO₃⁻ + H⁺
If the pH of the blood increases, one would expect

• A)a decrease in the concentration of H₂CO₃ and an increase in the concentration of H₂O.
• B)an increase in the concentration of H₂CO₃ and a decrease in the concentration of H₂O.
• C)a decrease in the concentration of HCO₃⁻ and an increase in the concentration of H₂O.
• D)an increase in the concentration of HCO₃⁻ and a decrease in the concentration of H₂O.
• E)a decrease in the concentration of HCO₃⁻ and an increase in the concentration of both H₂CO₃ and H₂O.
