 The increased solubility of Mg(OH)2 when acid is added is demonstrated and explained at the molecular level.
Notes
 Dissolution of Mg(OH)2 by acid. The increase in the solubility of Mg(OH)2 (milk of magnesia) on addition of an acid is demonstrated. This increase in solubility is also illustrated at the molecular level. H3O+ ions give a proton to the OH- ions, resulting in the production of H2O. As the OH- ions react, Mg2+ ions are released into solution. The overall reaction is Mg(OH)2 + 2HCl ----> MgCl2 + 2H2O and the net reaction is Mg(OH)2 + 2H3O+ ----> Mg2+ + 4H2O
