We can add a small amount of a diluted solution of a strong acid (which corresponds to a sharp increase in the concentration of \text {H}^+ H+. Our buffer solution will react to this addition by shifting its equilibrium.
WebJan 30, 2024 · Human blood contains a buffer of carbonic acid ( H 2 CO 3) and bicarbonate anion ( HCO 3 −) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid. Furthermore, the carbonic acid in the first ...
