I don't know about percentages, but since sea water has a lot of salt, I would expect that to be sodium and chlorine. (That is the common table salt; sea water also has some other salts.)
Coordination number of an ion is the number of oppositely charged ions present around that ion as the neighbour ions , in that ionic crystal.
Na+ and Cl- are spectator ions.
The negative ions are chloride, bicarbonate, and phosphate
calcium ions that has lost electrons. It will give away electrons.
The arrangement of atoms or ions in a crystal.
These ions are Na+ and Cl-.
sulfate
The most predominant ions in seawater are Na+,Mg+,I-,cl-.
The chemical composition of urine varies widely depending upon the food and fluid intake.The components of urine are water and solutes. There is approximately 95 percent water in urine and the solutes are classified as ions and organic molecules.
It should say, "Magnesium and CHLORINE make up most of the ions in seawater." Not chloride.
Reverse Osmosis
Specific gravity is determined by the solutes in the urine - the less solutes, the lower the specific gravity. In normal urine, the solutes are ions such as ammonium.
It contains few ions. Dirty water conducts electricity very well. Or Salt water. Pure water has no solutes and lacks ions usually associated with solutes.
The four MAIN IONS in seawater in descending order of abundance are: CI: Chloride Na: Sodium SO4: Sulfate Mg: magnesium Found in Leckie-Yuretich: Investigating the Ocean, Page 114, Seawater Salinity: The salt of the Ocean
The more H2CO3 there is in seawater, the greater the number of hydrogen ions present. This decreases the pH of seawater, making it more acidic. Higher concentrations of H2CO3 also lessen the number of available carbonate ions (CO32).

a base is one that produces hydroxide ions
