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+), as noted below
If the pH of 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 H2CO3 and H+
