- Seawater - WikipediaSeawater, or sea 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, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium ( Na+. ) ions ).
- Seawater: Composition and Properties | SpringerLink3.1.1 Composition. Seawater contains an abundance of organic and inorganic constituents. These are present in dissolved, suspended, very finely distributed, or colloidal form. The dissolved constituents of seawater can be assigned to the following main categories:
- Key Physical Variables in the Ocean: Temperature, Salinity, and DensityThe physical properties of seawater include both 'thermodynamic properties' like density and freezing point, as well as 'transport properties' like the electrical conductivity and viscosity.
- Chemical and physical properties of seawater | Britannicaseawater, Water that makes up the oceans and seas. Seawater is a complex mixture of 96.5% water, 2.5% salts, and small amounts of other substances. Much of the world’s magnesium is recovered from seawater, as are large quantities of bromine. In certain parts of the world, sodium chloride (table salt) is obtained by evaporating seawater.
