One of the Buffers That Contributes to PH Stability in Human

question 90

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+.
