Mg2Salze
Mg2Salze, or magnesium(II) salts, are chemical compounds containing the Mg2+ cation paired with various counteranions. The Mg2+ ion is small and highly charged, which yields high lattice energies and influences solubility and hydration behavior. In water, Mg2+ is strongly hydrated, typically as the octahedral complex [Mg(H2O)6]2+. Many magnesium salts crystallize as hydrates (for example MgSO4·7H2O, MgCl2·6H2O), though some exist as anhydrides.
Common examples include magnesium chloride (MgCl2), which is highly soluble; magnesium sulfate (MgSO4), used in medical
Preparation of magnesium salts typically arises from reactions of magnesium sources (for example Mg metal, MgO,
Applications are diverse: Mg salts serve as dietary supplements and laxatives (MgSO4, Mg hydroxide), in agriculture
