Properties of Sea Water

 

Physical Properties


1. "Density": Seawater is denser than


 freshwater, with an average density of around


 1.03 g/cm³.


2. "Salinity": Seawater has a high salinity, with


 an average of around 3.5% (35 parts per


 thousand).


3. *Temperature": Seawater temperature


 varies depending on location and depth, 


ranging from around -1.8°C to 30°C.


4. "pH": Seawater has a slightly alkaline pH,


 ranging from around 7.9 to 8.4.



Chemical Properties



1. "Major ions": Seawater contains a variety of


 ions, including sodium, chloride, magnesium,


 sulfate, and calcium.


2. "Nutrients": Seawater contains essential


 nutrients for marine life, such as nitrogen,


 phosphorus, and iron.


3. "Dissolved gases*: Seawater contains


 dissolved gases, including oxygen, nitrogen, 


and carbon dioxide.


4. "pH buffering": Seawater has a natural pH


 buffering capacity due to the presence of


 bicarbonate and carbonate ions.



Biological Properties


1. *Marine life": Seawater supports a vast


 array of marine life, from tiny plankton to


 massive blue whales.


2. "Primary production": Seawater is the site 


of primary production, where phytoplankton


 convert sunlight into organic matter.


3. "Decomposition": Seawater is also the site 


of decomposition, where organic matter is


 broken down by microorganisms.


4. "Nutrient cycling": Seawater plays a critical


 role in nutrient cycling, with nutrients being


 exchanged between the ocean and the


 atmosphere.


Other Properties


1. "Viscosity": Seawater has a higher viscosity


 than freshwater, due to its higher salinity and


 density.


2. "Surface tension": Seawater has a higher


 surface tension than freshwater, due to its


 higher salinity and density.


3. "Optical properties": Seawater has distinct


 optical properties, including absorption and


 scattering of light.



4. "Acoustic properties": Seawater has distinct


 acoustic properties, including the speed and


 absorption of sound.
