Chemical weathering and out gassing
Oceans are salt water, so sodium and chlorine are present in pronounced quantities. But oxygen, carbon dioxide (CO2, which is carbon and oxygen) and a number of other important elements are also present. Consider that if there was no oxygen, fish and a number of other organisms would die. That makes the dissolved oxygen pretty darn important.
The major dissolved components of seawater are salts and other materials from the crust of the earth. However, water accounts from over 96% of the composition of seawater.
sodium and chlorine
Your Mom xD
H2O+NaCl
Chemical weathering and out gassing
water, salt and urine
For seawater about 10ppb.
Seawater is neither a compound nor an element but a mixture including much dissolved solid and usually microorganisms as well.
Salinity
Chemical weathering and out gassing
outgassing of elements from Earth's interior.
Salinity is the total amount of the solid materials DISSOLVED in water

Dissolved salts are transported by the rivers.
The most negatively charged ion dissolved in seawater is chloride. In fact, Cl- makes up 55 percent of the seawater's salinity.

Desalination.
These ions are Na+ and Cl-.
