CHEMISTRY GLOSSARY

Salt water is the water of the sea and the ocean. This water contains a relatively high percentage of dissolved salt (about 35 g of salt per 1 000 g of sea water.). About 90 % of that salt would be sodium chloride, or ordinary table salt.

The salinity of ocean water varies. It is affected by such factors as melting of ice, inflow of river water, evaporation, rain, etc.
