Seawater is a mixture of different elements and compounds. It is primarily composed of water and contains dissolved salts, minerals, and other substances. So, seawater is not an element but a complex mixture of different compounds.
Iodine is a naturally occurring element that is found in the Earth's crust and in seawater. It can also be extracted from minerals and seaweed as well as produced synthetically for various industrial applications.
Bromine is mainly obtained from natural brine deposits, which are underground reservoirs containing high concentrations of salts. The brine is extracted and treated to remove impurities, after which bromine is extracted through evaporation and chemical processes. Another method is through seawater, where bromine is extracted by treating seawater to concentrate and purify the bromine content.
Chlorine is extracted from seawater using a process called electrolysis, where an electric current is passed through the saltwater to split it into its components. Chlorine is collected at the anode during this process.
Lithium is typically found in mineral deposits, such as spodumene and petalite, as well as in salt flats like those found in Chile and Argentina. It can also be extracted from seawater and geothermal brines.
Gold has been extracted from seawater, but the cost is not worth the effort for the very small amount that can be obtained.
Halite (NaCl) is extracted by mining or from seawater by crystallization/recrystallization.
aluminium
Sodium chloride is extracted from mines or seawater.
the main element extracted was radium
Seawater is a mixture of different elements and compounds. It is primarily composed of water and contains dissolved salts, minerals, and other substances. So, seawater is not an element but a complex mixture of different compounds.
No; seawater is essentially a mixture of water, salt and other substances such as sand.
Salt (sodium chloride, NaCl) is extracted from salt mines or seawater.
Einsteinium is not extracted from the earth, it is an artificial element.
The chemical element found in sea water and used as a fire retardant is bromine. It is extracted from seawater and is widely used in fire retardant materials due to its ability to inhibit the spread of flames.
Lithium is extracted as the molten metal by a process of electrolysis.
