OccurrenceMgCl2, is one of the primary constituents of seawater and occurs in most natural brines and salt deposits formed from the evaporation of seawater.
VerwendenMagnesium Chloride is a source of magnesium, a color-retention agent, and firming agent. it exists as colorless flakes or crystals and is very soluble in water.
synthetischeIn the “Dow Process” (which is the electrolytic method of extracting bromine from brine), magnesium chloride is regenerated from magnesium hydroxide by hydrochloric acid: Mg(OH)2(s)+2HCl→MgCl2(aq)+2H2O It can also be prepared from MgCO3 by a similar reaction. Magnesium chloride is ionic and so will undergo electrolysis when it is molten. Electricity is carried by the movement of the ions within the melt and their discharge at the electrodes. However, solid magnesium chloride is a nonconductor of electricity because the ions are immobile.
