Examples include distilled water, elemental gold, or table salt, each maintaining a consistent molecular structure. Magnesium and sulfate contribute to the salinity levels.
Distillation Isolating Pure Water from Sea Water
A pure substance has a constant composition and distinct properties that do not vary from sample to sample. While the phrase "sea salt" might imply purity, the reality is far more complex.
Chemical Composition of Sea Water The primary component of sea water is, of course, water (H₂O), but it is the dissolved substances that define its character. The most abundant salts are sodium chloride, magnesium chloride, and calcium sulfate, collectively creating the brackish environment familiar to oceanographers.
Distillation Isolating Pure Water from Sea Water
Distinguishing Mixtures from Pure Substances Physical methods can easily separate the components of sea water, highlighting its status as a mixture. 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.
