WebWhat this means is that even though the total amount of salt dissolved in seawater can vary from 32 to 39 grams per kilogram, the ratio of each major ion to each other major ion stays exactly the same. For instance the ratio of sodium to chloride (in molar units) is 0.859 in seawater of salinity 32 and in seawater of salinity 35. WebSome elements—chlorine, bromine, boron, and sulfur—are present in seawater in amounts far in excess of those that can have been derived by erosion. The source of these “superabundant” elements has probably been volcanism and related magmatic activity.
