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
What are the properties of sea water?
Sea water contains common salt (sodium chloride - N a C l) and other compounds which, when dissolved in water dissociate into ions (in the case of N a C l, it produces N a + and C l ? ions). These ions, being charged particles, can conduct electricity.
What are the chemical elements present in seawater?
Chemical elements in sea water do not exist on their own but are attracted to preferential ions of opposite charge: sulphur will occur mainly as sulphate, sodium as sodium chloride, and so on. Detailed composition: abundance of the elements in seawater
What causes variations in seawater properties?
Variations in the seawater properties are caused by many factors including atmospheric heating and cooling, precipitation, and for dissolved oxygen, gas exchange with the atmosphere and biological respiration. Listed below are some standard time series plots generated on a daily basis to reveal the state of the ocean at each site.
What is the specific weight of seawater?
At this depth the specific weight of seawater is approximately 10,520 N/m3. At the surface, b 10,050 N/m3. Estimate the absolute pressure at this depth, in atm. Dry adiabatic lapse rate (DALR) is defined as the negative value of atmospheric temperature gradient, dT/dz, when temperature and pressure vary in an isentropic fashion.
