英文摘要 | The effects of calcium and magnesium ion concentrations in artificial seawater (ASW) on the equilibrium state of the system H �� CO �� - H �� O have been tested. The measured first and second apparent dissociation constants of carbonic acid, K' �� and K' ��, increase with an increase in the concentrations of calcium and magnesium in ASW. The total and free activity coefficients of HCO �� -and CO - at the ionic strength of 0.718 and temperature of 25 ℃ decrease as a function of Mg:Ca concentration ratios in ASW. The results also show that the calcium ion has a greater effect on the apparent dissociation constants of carbonic acid than magnesium, suggesting that the calcium ion associates more strongly with bcarbonate and carbonate than the magnesium ion does. |
