Describe the chemical composition of seawater
What will be an ideal response?
Seawater is a solution. The concentrations of dissolved solids in seawater is known as salinity. Seawater has a rather uniform chemical composition, which is affected by the atmosphere, minerals, bottom sediments, and living organisms. Seven elements account for more than 99% of the dissolved solids in their ionic form: chlorine (CL-), sodium (NA+) , magnesium (Mg2+), sulfates (SO42), calcium (CA2+), potassium (K+), and bromine (BR-). The average worldwide salinity of seawater is 35‰. However, the values actually vary worldwide from about 34‰ to 37‰. Areas with freshwater inputs (equatorial regions, near coastlines) tend to have lower salinity, whereas areas with high evapotranspiration (e.g. subtropical high areas) have higher salinity.
