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
