What is the difference between sodium hydroxide and potassium hydroxide?
There is not a lot of difference. They are both powerful bases but potassium hydroxide is more expensive. Sodium hydroxide is manufacture by electrolysis of seawater. Potassium Hydroxide just does not have a cheap source of raw material as seawater!
Why are so few metals extracted from sea water?
Most metals are not in any economic concentrations in seawater. The only exceptions are sodium and magnesium. A company did start up trying to extract lithium from seawater but it went bust but the technology will certainly be looked at again when lithium is needed in large amounts for making batteries. Bioengineering technology may be used in the future to get bacteria and algae to concentrate metals from seawater.
What is the name of Magnesium ore?
Magnesium is an essential element in your diet. Green spinach and many other green vegetables are useful sources.answer 2 Magnesium is commonly extracted from sea water, and for this purpose, you need warm sea water [for economics] and a plentiful supply of sea shells or other calcium source such as limestone. It is prepared using a flux electrolytic process in a similar manner to that for aluminium. Dolomite rock is another commercial source for this useful metal.
What causes the density of seawater to increase?
The density of seawater increases if salinity increases.
How much seawater is there versus fresh water?
97% seawater, other 3% is freshwater.
What element can be extracted from seawater?
Magnesium
Does magnesium chloride dissolve in seawater?
Magnesium chloride is soluble in water.
When seawater evaporates the concentration of salts increases until what?
precipitate out the solution
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.
How do you separate magnesium from seawater?
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.
Why is extraction of magnesium in seawater important?
because it just is :D
What do many organisms take from seawater to make bones or shells?
They take magnesium.
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.
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
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
Is magnesium and chlorine a likely compound?
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.
