ás del 70 por ciento de la Tierra está ocupado por agua. Pero el agua de
         mar no es agua pura, sino que contiene ciertas cantidades otras materias,
         bien disueltas, bien en suspensión. La composición química del agua del
         mar es descrita a menudo en trabajos que parecen escritos por alquimistas
que, dejándose arrastrar por su imaginación, la describen compuesta por toneladas
de metales preciosos.

Es cierto que el mar contiene, diseminados en el seno de sus aguas, algunos de
esos metales, pero su extracción, a escala industrial y económica, a pesar de los
repetidos ensayos hechos en muchos lugares, no es rentable.

Sin embargo, si estos metales no son, por el momento, aprovechados por el
hombre, la sal que el océano contiene, sabor que pueden apreciar todos los que la
prueban, ha sido altamente utilizada a través de la historia, por lo que su valor es
infinitamente superior al que podrían tener los metales.

Aunque la salinidad y la composición química varia de un mar a otro -lo que
comporta cambios de densidad así como otros parámetros físicos y químicos-
anotamos aquí la composición quimica media aproximada de 1 litro de agua de
mar:


          Componente                       Cantidad Unidades
          Cloruro de sodio                         24,0   gramos
          Cloruro de magnesio                       5,0   gramos
          Sulfato neutro de sodio                   4,0   gramos
          Cloruro de calcio                         1,1   gramos
          Cloruro de potasio                        0,7   gramos
          Bicarbonato de sodio                      0,2   gramos
          Bromuro de sodio                        0,096   gramos
          Ácido bórico                            0,026   gramos
          Cloruro de estroncio                    0,024   gramos
          Fluoruro de sodio                       0,003   gramos
          Agua destilada                          1.000   mililitros

                  (Salinidad aproximada 34.5%     -   pH 7.9-8.3)
