Another physiological example of an equilibrium system involves the regulation of blood pH. Carbon dioxide in the blood reacts reversibly with water to produce carbonic acid, which dissociates to produce hydronium and bicarbonate ions: CO2 (aq) + H2O (l) ⇔ H2CO3 (aq) ⇔ H3O+ (aq) + HCO3-(aq) Which of the following statement/s is/are TRUE? During strenuous exercise, the amount of carbon dioxide produced by the cells increases as a result of high metabolic activity. The increased concentration of carbon dioxide in the blood causes a shift to the right in this equilibrium to produce more carbonic acid. When this happens, the pH level of the blood increases as hydronium ion concentration increases. One of the body's responses to this imbalance in blood pH is to increase the rate of breathing so more carbon dioxide gas is exhaled from the lungs, thus shifting the equilibrium back to the left and raising the pH back to normal levels.

4. Open bodies of water can act as carbon sinks due to the ability of carbon dioxide to dissolve in water. The dissolution of carbon dioxide produces carbonic acid (H₂CO3) which then partially dissociates in an equilibrium reaction important for controlling water pH. CO₂ (g) + H₂O (1)→ H₂CO3(aq) H₂CO3 (aq) H+ (aq) + HCO3(aq) The equilibrium between carbonic acid (H₂CO3) and bicarbonate (HCO3) is influenced by the presence of dissolved metals from the bedrock underlying a body of water. Calcium from limestone (a type of sedimentary rock formed from marine exoskeletons) is one such metal. The graph below shows how the concentration of dissolved calcium ions (measured in parts per million, or mg/L) affects the concentration of carbon dioxide dissolved in ocean water (measured partial pressure). Based on this graph and your understanding of equilibrium, in what direction does the presence of limestone shift the carbonic acid/bicarbonate equilibrium? 10-4 10-3 Closed Calcite saturation-…
