Properties are listed as a function of temperature and salinity for the pressures P = P0 7 MPa and 12 MPa Here P0 = 0 101325 MPa for t 100 °C is the vapor pressure of seawater For P = 7 MPa and 12 MPa only the properties with pressure dependence are listed
Properties of Seawater Water is called the universal solvent because of its ability to dissolve at least a little of virtually every substance Water is a particularly good solvent for substances held together by polar or ionic bonds Indeed the most abundant substances dissolved in seawater are ionic solids (salts such as sodium chloride)
1 Seawater can be thought of as a solution The dissolving agent or solvent is liquid water (H 2 O) and the materials dissolved in water such as salt are the solutes 2 The majority of seawater is pure water (H 2 O) typically over 90 3 The major seawater constituents are seven dissolved salts that account for over
Seawater is an aqueous electrolyte solution of several solutes referred to as sea salt The chemical composition of sea salt is very similar in all oceans and varies negligibly with time The mass fraction of dissolved material in seawater is termed its absolute salinity
There are several other colligative properties that we see in seawater: 1 Boiling point elevation 2 The higher the concentration of ions (or molecules) in solution the higher is the boiling point of the solution For seawater with a salinity of 35 the boiling point is higher by about 0 3 deg C 3 Freezing point depression 4
Seawater is a complex solution containing dissolved inorganic salts (3 5 ) dissolved gases and traces of dissolved organic molecules Chemical and physical exchanges at the interface between the ocean and atmosphere have profound effects on the heat budget and climate of the Earth
