What are the physical and chemical characteristics of seawater?

Physical and Chemical Characteristics of Seawater Seawater is a mixture of various salts and water. Most of the water in the ocean basins is believed to originate from the condensation of water found in the early atmosphere as the Earth cooled after its formation. This water was released from the lithosphere as the Earth's crust solidified.

What factors affect the density of sea water?

Density: the density of sea water depends on temperature and salinity Dissolved gases: the two important gases to life, oxygen and carbondioxide. Limiting hydrogen ions and ocean pH.

How does salinity affect the chemical composition of seawater?

The chemical composition of seawater. As salinity increases, the amount of gas dissolved decreases because more water molecules are immobilised by the salt ion. As water temperature increases, the increased mobility of gas molecules makes them escape from the water, thereby reducing the amount of gas dissolved.

What is the pH of seawater?

Seawater generally has the pH of 7.5 to 8.4. Chemical analysis of seawater is the great way to deeply understand the chemical containment in the seawater. One of the important chemical analysis of seawater is the salinity level. It’s the amount of the salt dissolved in the seawater.
