A decade of results in Scandinavia indicate that as lakes are subjected to acidic precipitation, cations are mobilized, and that some of the bicarbonate ions are replaced by sulphate, thus, the normal relationship between the dominant cations, calcium and magnesium, and alkalinity, appears to be altered.  1, record 1, English, - bicarbonate%20ion

However, whereas our results and those of Beamish and Van Loon (1977) found H+ to be the dominant cation, Schindler et al. (1976) and Kramer (1976) reported Ca++ and Mg++ respectively to be most abundant.  1, record 2, English, - dominant%20cation

Changes in the acidity of precipitation are reflections of changes in the balance between the major cations and anions in precipitation. Thus, to understand the acidity of precipitation, it is essential to measure all the major anions and cations in precipitation(especially H+, SO4=, NO3-, and NH4+, but also including K+, Na+, Ca+, Mg++, C1-, HCO3-, SO3=, and PO4=).  2, record 2, English, - dominant%20cation

Cations majeurs : parmi ceux-ci Ca++ est prépondérant à raison de 45 à 60% et, ensuite, suivent Mg++ (20 à 25%), Na+ (15 à 24%) et K+ (4 à 8%). De manière générale, les concentrations de ces cations s'avèrent basses dans les rivières concernées (117 à 206 [microéquivalents par litre] pour Ca++, 59 à 80 [microéquivalents par litre] pour Mg++, 50 à 80 [microéquivalents par litre] pour Na+ et 36 à 62 [microéquivalents par litre] pour Na+ d'origine non marine et, enfin, 14 à 20 [microéquivalents par litre] pour K+ en moyennes/station) : cela montre que leurs eaux sont peu minéralisées et peu dures.  5, record 2, French, - cation%20majeur

What determines the chemistry of rain and snow? The water comes from evaporation and transpiration(water vapor lost by plants) and is essentially distilled, or pure. Once the vapor reaches the atmosphere, however, it condenses on solid particles and soon reaches equilibrium with atmospheric gases. One of the gases is carbon dioxide(CO2), and as carbon dioxide dissolves in the water carbonic acid(H2CO3) forms. Carbonic acid, being a weak acid, dissociates only slightly in distilled water, yielding hydrogen ions and bicarbonate ions(HCO3-). At normal concentrations and pressures of carbon dioxide in the atmosphere the pH of rain and snow would be 5. 6.  1, record 4, English, - chemistry%20of%20snow
