Web20 jan. 2024 · The remarkable thing about seawater is the constancy of its relative ionic composition. The overall salt content, known as the salinity (grams of salts contained in 1 kg of seawater), varies slightly within the range of 32-37.5%, corresponding to a solution of about 0.7% salt content. WebSix major ions make up >99% of the total dissolved in seawater. They are sodium ion (Na+), chloride (Cl-), sulfate (SO42-), magnesium ion (Mg2+), calcium ion (Ca2+), and potassium ion (K+). 4.
