Detailed explanation-1: -Two of the most prevalent ions in seawater are chloride and sodium. Together, they make up around 85 percent of all dissolved ions in the ocean. Magnesium and sulfate make up another 10 percent of the total. Other ions are found in very small concentrations.
Detailed explanation-2: -Hydrogen and oxygen make up most of seawater. These elements make up the water molecule and parts of other compounds and are so abundant they are considered to be in their own category.
Detailed explanation-3: -All salt is sodium chloride, and it all comes from the sea. All salt is sodium chloride (NaCl), and it all comes from seawater-even table salt.
Detailed explanation-4: -Chloride and sodium, the components of table salt (sodium chloride NaCl), make up over 85% of the ions in the ocean, which is why seawater tastes salty (Figure 5.3. 1). In addition to the major constituents, there are numerous minor constituents; radionucleotides, organic compounds, metals etc.
