Using solution theory and the aide of tables and graphs, explain why the delta h solution for sodium chloride is favorable to the formation of an aqueous solution of sodium chloride.

The solution is non-ideal for NaCl soln so ΔH3 is greater than the sum of ΔH1 and ΔH2. this means the forces of attraction between like molecules is greater than the forces of attraction between unlike molecules. NaCl (table salt) dissolves readily in water. In solid NaCl, the positive sodium ions are attracted to the negative chloride ions. The same is true of the solvent, water; the partially positive hydrogen atoms are attracted to the partially negative oxygen atoms. While NaCl dissolves in water, the positive sodium cations and chloride anions are being stabilized by the water molecule electric dipoles. Thus, the intermolecular bonds between NaCl are broken and the salt is dissolved.
