The chemical composition of sea water is relatively simple to interpret - it's H2O with a few extras. If you collect a sample of ocean water and take it to the laboratory, a chemist will quickly identify six major ions. He or she will detect chloride (Cl−), sodium (Na+), sulfate (SO24−), magnesium (Mg2+), calcium (Ca2+), and potassium (K+).
