Here the important ions added are the ones most abundant in seawater, namely the cations Na+ and Mg++ (sodium and magnesium), the anion Cl- (chloride) and to a lesser extent cations of calcium and potassium (Ca++, K+) and anions of sulfate (SO4--). 1, record 1, English, - cation%20of%20calcium

To be acidic rain must also have more sulphate (SO4=) and nitrate (NO3-) anions as compared to calcium (Ca++) and magnesium (Mg++) cations for example. The excess anions are then balanced by hydrogen ions (H+) making rain acid. 3, record 1, English, - cation%20of%20calcium

Le taux du calcium sanguin ou calcémie (100 mg/l) est une constante biologique. Elle est le reflet de l'équilibre métabolique de ce cation dans l'organisme [...] Enfin l'ion Ca2+ est l'effecteur d'enzymes protéolytiques comme la trypsine ou les thromboplastiques. 6, record 1, French, - cation%20calcium
