Any two ions held together make up salt. In fact 'salt' a simple name for ANY ionic compound.
Most likely you were referring to 'table salt' or what is commonly referred to as just salt.
Table salt is sodium chloride (NaCl) which is an ionic solid (and therefore is one of the many salts).
The two ions in it are Na+ and Cl- .
Na+ and Cl- for salinity.
Added:
Water itself is only partially (weakly) ionised, giving about equal amounts (1.0*10-7 mol/L) H+ and OH- ions if sea were to be neutral (so at pH about 7). This is very low as compared to 55.5 mol/L H2O and even to the (about) 0.5 mol/L NaCl which is fully ionized.
Chloride, sodium, sulfate, magnesium, calcium and potassium in that order. You will find a fuller list in this link:http://www.lenntech.com/composition-seawater.htm
The last 2 are always present in water, regardless of any others.
The answer is B) Chloride and sodium
hydrogen and oxygen ions and some times impurities
OH- and H+
Ions - atoms with an electrical charge. Actually, pure water is a good insulator, but most naturally-occuring water contains some ions, and will therefore conduct electricity.
Water is an electricity conductor because: - extremely pure water is difficult to obtain and store - hydrolysis of water lead to ions H+ and OH-

chloride and sodium
Ocean water is a complex mixture of substances, the two most common being water, of course, and common salt (sodium chloride). Waer is a covalent substance and only splits into ions to a very small degree. Sodium chloride, however, is an ionic substance and splits into two ions, sodium ions (Na+) and choride ions (Cl-). So these two iions are the most common.The first is Chloride, and the second is Sodium.
Tap water may contain multiple ions and minerals. A common ion found in water are fluorides, which is added to benefit dental health.
If the water is pure, it will contain H3O+ ions and OH- ions. They are hydronium ions and hydroxyl ions.
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
There are several things in ocean water.Mainly found water.Then there are ions like Na,Cl,Mg,Ba,Sulphates,Br etc...Also there are micro organisms,organic materials according to pollution.
This question depends on what importance is being assigned. The most common dissolved ions (elemental atoms do not dissolve) are sodium and chloride, but they are many other important elements found in sea water.
A solution of Na+(sodium ions) and Cl-(chlorine ions) in water is brine.
hydrogen and oxygen ions and some times impurities
The main difference between distilled and bottle water is the ions and minerals found in them. In distilled water, no ions nor minerals can be found while in bottled water such elements are present. The taste is also different due to the ions present (or absent in the case of distilled water) in the water. !!
Oxygen (in Oxide ions)
OH- and H+
