First, the sea water is collected in large basins and heated to evaporate some of the water. This yields a concentrated solution of water and various salts which are mixed with calcium hydroxide (lime) to yield a magnesium hydroxide precipitate. The precipitate is then reacted with hydrochloric acid to yield magnesium chloride. This is then separated into molten magnesium metal and chlorine gas ions through the electrolysis process. The chlorine is reacted with hydrogen to yield hydrochloric acid to be recycled, while the molten magnesium is then cast into ingots.
filtration
allow centrifugation
not
decanting
not
evaporation, crystallisation
well you would have to split sea water to what its made of... Sodium chloride, Magnesium Chloride and Calcium Chloride and other stuff, now on the reactive scale where abouts is magnesium compared to the other elements?
Magnesium is at the bottom of calcium, and sodium is above calcium, so in other words no it wouldn't react because calcium metal and sodium metal cant be precipitated out of solution due to the reactivity of those elements
You would need a water softener or if your using cartridges then you would use a DI or a water softening cartridge.
Magnesium react with water, especially as a fine powder or at high temperature.
Magnesium chloride is soluble in water.
because it just is :D
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.
You can separate the salt from the water. You need a special machine to separate salt from the water. but its very hard to do. I hope i answered your Question.
It should say, "Magnesium and CHLORINE make up most of the ions in seawater." Not chloride.
because it just is :D
how much sodium hydroxide in grams must be added to seawater to precipitate 86.9mg of magnesium present?
by evaporation
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
