because it just is :D
Magnesium chloride is soluble in water.
For example in the process of table salt extraction from the seawater.
Magnesium can be extracted from the minerals Dolomite (CaCO3·MgCO3) and Carnallite (KCl·MgCl2·6H2O), but is most often obtained from seawater
Sodium chloride, potassium chloride, magnesium chloride
It's an actual, and common, compound - MgCl2 (magnesium chloride), a constituent of seawater, has many uses including just chasing off the chlorine atoms to recover the magnesium metal.
Magnesium
Magnesium chloride is soluble in water.
Seawater is first filtrated and then refined by repeated processes of crystallization/dissolving/recrystallization.

The most important salt in the seawater is sodium chloride; also exist magnesium, calcium and potassium chloride.
It should say, "Magnesium and CHLORINE make up most of the ions in seawater." Not chloride.
how much sodium hydroxide in grams must be added to seawater to precipitate 86.9mg of magnesium present?
The most important salt in sea water is sodium chloride; other salts are chlorides of potassium, calcium and magnesium.
They take magnesium.
When fresh water is removed from ocean water, the salts that are left behind are also a valuable resource. Over half of the world's supply of magnesium, a strong, light metal, is obtained from seawater in this way.
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
