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⁺) . (See figure.) If the pH of blood drops, one would expect ________.

• A) a decrease in the concentration of H₂CO₃ and an increase in the concentration of HCO₃-
• B) the concentration of bicarbonate ions (HCO₃-) to increase
• C) the HCO₃- to act as a base and remove excess H⁺ by the formation of H₂CO₃
• D) the HCO₃- to act as an acid and remove excess H⁺ by the formation of H₂CO₃
