Salinity of seawater is usually expressed as the grams of salt per kilogram (1000 g) of seawater. On average, about 35 g of salt is present in each 1 kg of seawater, so we say that the average salinity of the ocean salinity is 35 parts per thousand (ppt). Note that 35 ppt is equivalent to 3.5% (parts per hundred).

WebUses. Sodium is used as a heat exchanger in some nuclear reactors, and as a reagent in the chemicals industry. But sodium salts have more uses than the metal itself. The most common compound of sodium is sodium chloride (common salt). It is added to food and used to de-ice roads in winter. WebThat is, sodium is a cation element. Na – e – → Na +. The electron configuration of sodium ion (Na +) is 1s 2 2s 2 2p 6. This electron configuration shows that sodium ion (Na +) has acquired the electron configuration of neon (Ne) and it achieves an octave full stable electron configuration.
