WebAluminium is a 3+ ion whereas magnesium is only 2+. Aluminium is also a smaller ion so the effective electrostatic attraction on the valence electrons should be greater. I'm also pretty sure aluminum oxide has greater covalent charterer than magnesium oxide. WebOct 13, 2015 · MgO has a high lattice energy of about 4000 KJ/mol. Also MgO is insoluble in water because the atoms are tightly held. MgO has a rock salt structure. – Aditya Dev Oct 13, 2015 at 13:43 3 That's true, but hardly explains anything. Again, CaO has the same structure. – Ivan Neretin Oct 13, 2015 at 15:53
WebHCl + MgO is a double displacement type of reaction. Here O2- gets replaced by Cl– to form the MgCl2 salt and water as the product.
