Salinity, temperature, turbidity, pH, buffering capacity, dissolved oxygen, and nutrient levels.
Seawater does not have a density of 5.
When ice forms from seawater, the remaining seawater becomes saltier because the ice is primarily composed of freshwater. As the ice freezes, it excludes most of the dissolved salts, leading to an increase in salinity in the surrounding water. This process can affect local marine ecosystems and influences the density and circulation of seawater. Consequently, the remaining seawater's properties change, which can impact marine life and ocean currents.
The critical pressure of seawater, which is the pressure above which water cannot exist as a liquid regardless of temperature, is approximately 22.1 megapascals (MPa) or about 220 atmospheres. This value can vary slightly depending on the salinity and temperature of the seawater. At this pressure, seawater transitions to a supercritical fluid state, exhibiting properties of both liquids and gases.
Seawater is a mixture. It consists of water (H₂O) along with various dissolved salts, minerals, and organic matter. Unlike a compound, which has a fixed composition and properties, the composition of seawater can vary based on location and environmental factors.
The seawater that has remained relatively stable in its composition for hundreds of years is often referred to as "conservative seawater." This term highlights the consistency of its major ions and properties, which are less affected by biological or chemical processes over short time scales. The concept is crucial in oceanography for understanding ocean circulation and the global carbon cycle.

Seawater is considered to be homogeneous because it is a mixture of various salts and minerals that are evenly distributed throughout. This means that properties such as salinity and temperature are consistent throughout the body of seawater.
When seawater is decomposed, toxic chlorine gas can be produced. This can happen when an electric current is passed through seawater during the process of electrolysis. It is important to handle and dispose of chlorine gas safely due to its toxic properties.
Conductivity can be used to calculate the salinity of the water.

Seawater is water with salt in it
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
