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.

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


What does magnesium come from?

Magnesium is a naturally occurring element found in the Earth's crust. It is commonly extracted from minerals such as magnesite and dolomite through mining and refining processes. Magnesium can also be obtained from seawater and brine sources through extraction and purification techniques.


Why are the sources of magnesium compounds such as magnesium chloride in seawater?

Magnesium compounds like magnesium chloride are abundant in seawater due to the natural weathering of rocks on land, which releases magnesium into rivers that eventually flow into the oceans. Additionally, magnesium is a significant component of oceanic minerals, and its solubility allows it to remain dissolved in seawater. The continuous cycle of evaporation and precipitation also helps concentrate magnesium salts in marine environments. Thus, seawater serves as a major reservoir for magnesium compounds.

Ocean water contains 3.5 g NaCl by mass How much salt can be obtained from 274 g of seawater?

To find how much salt can be obtained, we need to calculate the mass of NaCl in 274 g of seawater. Since the concentration of NaCl in seawater is 3.5 g per 100 g of water, the mass of NaCl in 274 g of seawater is 9.59 g. Therefore, 9.59 g of salt can be obtained from 274 g of seawater.
