Which will likely be more soluble in water, MgO or NaCl? Explain briefly the thermodynamic reason for your answer.
Homework Answers
In NaCl the ionic bond between Na+ & Cl- can easily be
destroyed by the dielectric energy of water solvent.
In MgO the bond is between Mg2+ & O2-.Mg2+ ion & O2- ion
are smaller in size than Na+& Cl- ions respectively. As such
the ionic bond between them is stronger than that between Na+
&Cl-. The energy associated with water is not enough to break
it. Hence MgO is insoluble in water
