It is usually prepared by the electrolysis of magnesium chloride, MgCl 2, at a temperature a little above its melting point of 715°C. For example, the solubility of NaF in water at 25°C is 4.13 g/100 mL, but under the same conditions, the solubility of MgO is only 0.65 mg/100 mL, meaning that it is essentially insoluble. We have discussed the inverse relationship between the size of the ions and the magnitude of lattice energy released when the ions form a bond.
