WebPart 3: Buffers in the Blood . Bicarbonate ions act as a powerful buffer in your blood. They are created when carbon dioxide (CO 2), produced during cellular respiration, reacts with water:. CO 2 + H 2 O ↔ H 2 CO 3 ↔ HCO 3– + H+. Notice that hydrogen ions are also generated, which increases the acidity of blood and decreases the pH. WebExample. Thus, the pH of an acidic solution of HNO 3 (10 –3 M) = 3, a basic solution of KOH having [OH –] =10 –4 M and [H 3 O +] =10 –10 M will have a pH = 10. pH of acids is generally less than 7 whereas for bases it is greater than 7.
