Which of these two ionic compounds has the higher melting

Dec 11, 2016· I suppose it is the "alumina". For sodium chloride, each of the constituent ions have unit charge. For alumina, the ionic lattice is composed of Al^(3+) and O^(2-) ions. Because the electrostatic force of attraction should be greater we would predict that alumina should have the greater melting point. The aluminum ion is also smaller than the sodium ion and thus more polarizing.
