Finally (Ca ++)(HCO 3) 2 = x 106 (CO 2 air) In other words, the calcium in solution is directly proportional to the partial pressure of CO 2. If we assume the bicarbonate forms solely from the equilibrium between carbonic acid and calcium carbonate, then the calcium content is proportional to the cube root of the partial pressure.
