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.
What else can I help you with?
Does magnesium chloride dissolve in seawater?
Magnesium chloride is soluble in water.
Why is extraction of magnesium in seawater important?
because it just is :D
How is magnesium carbonate obtained?
Magnesium can be extracted from the minerals Dolomite (CaCO3·MgCO3) and Carnallite (KCl·MgCl2·6H2O), but is most often obtained from seawater
Two most abundant salts in seawater?
Sodium chloride, potassium chloride, magnesium chloride
How does one get magnesium it its pure form?
Magnesium is an abundant element on Earth. Magnesium is not found in a pure form because it bonds with other elements. A process has to be applied to get the Magnesium separated from the other elements.
How is magnesium obtained from seawater?
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.
Does magnesium chloride dissolve in seawater?
Magnesium chloride is soluble in water.
How is table salt produced from seawater how do you separate table salt from mother liquor magnesium chloride?
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.
What element can be extracted from seawater?
Sodium chloride (salt) is the most commonly extracted element from seawater. Other elements that can be extracted include magnesium, calcium, and potassium.
What is the mistake in this statement magnesium and chloride make up most of the ions in seawater?
It should say, "Magnesium and CHLORINE make up most of the ions in seawater." Not chloride.
Why is extraction of magnesium in seawater important?
because it just is :D
How do you separate fresh water from seawater?
by evaporation
How much sodium hydroxide in grams must be added to seawater to completely precipitate 86.9mg of magnesium?
To completely precipitate 86.9mg of magnesium from seawater, you would need to add an equal molar amount of sodium hydroxide. The molar mass of magnesium is about 24.3 g/mol, so 86.9mg is equivalent to about 3.57 mmol of magnesium. You would need the same amount of mmol of sodium hydroxide to completely precipitate the magnesium.
What do many organisms take from seawater to make bones or shells?
They take magnesium.
What are the six ions in seawater?
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
