This separability is a clear indicator that sea water lacks the defining characteristic of a pure substance, which requires a uniform and inseparable structure. Distillation, for instance, can isolate pure water from the salts, demonstrating that the substances are not chemically bonded in a fixed ratio.
The Ionic Dominance of Sodium Chloride in Sea Water
Examples include distilled water, elemental gold, or table salt, each maintaining a consistent molecular structure. Commercial sea salt is essentially a refined product derived from the evaporation of sea water, but it still contains remnants of other minerals and elements.
Sea water, however, is a solution containing water plus a wide variety of dissolved salts, gases, and organic materials, which immediately suggests it is not pure in the chemical sense. Furthermore, sea water contains suspended solids, microscopic organisms, and dissolved gases like oxygen and carbon dioxide.
The Sodium Chloride Dominance in Sea Water
While the phrase "sea salt" might imply purity, the reality is far more complex. Sea water fails this criterion because its composition changes depending on location, depth, and environmental conditions.
