The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys. Medical Subject Headings (MeSH) Web2, you would have to supply more energy to ionise the magnesium (1st + 2nd ionisation energies), but you would also get a lot more energy released when the lattice forms, because of the greater attractions involving the 2+ ions. The net effect is that the enthalpy change of formation of MgCl 2 is more negative than that of MgCl, meaning that MgCl
