One of the Buffers That Contributes to PH Stability in Human

question 70

Multiple Choice

One of the buffers that contributes 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 HCO₃⁻.
• B)an increase in the concentration of H₂CO₃ and a decrease in the concentration of HCO₃⁻.
• C)a decrease in the concentration of HCO₃⁻ and an increase in the concentration of H⁺.
• D)an increase in the concentration of HCO₃⁻ and a decrease in the concentration of OH⁻.
• E)a decrease in the concentration of HCO₃⁻ and an increase in the concentration of both H₂CO₃ and H⁺.
