`MgCl_(2).6H_(2)O` on heating gives anhydrous `MgCl_(2)`.

KCl.MgCl_2. 6H_2O is a

Anhydrous MgCl_(2) is obatined by heating hydrate salt, MgCl_(2).6H_(2)O .

Dow's process of extraction of Mg involves extraction of Mg from sea water. Sea water is concentrated in sun-light and is then treated with slaked lime. Magnesium hydroxide is heated in a stream of HCl to give MgCl_(2) which is electrolysed to discharge Mg. The mixture is in the ratio 35% MgCl_(2)+50% NaCl+15% CaCl_(2) . NaCl and CaCl_(2) are added to lower the fusion temperature and to increases the conductance.
