Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, or 600 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+.

This page details the chemical composition of sea water, salinity, density, its dissolved gases, carbon dioxide and pH as limiting factor. Salinity: the main salt ions making the sea salty. 2  Density: the density of sea water depends on temperature and salinity. 3  Dissolved gases: the two important gases to life, oxygen and carbondioxide. 4  Limiting hydrogen ions and ocean pH.
