1.	By using the following data draw an appropriate energy cycle & calculate the enthalpy change of hydration of (i) the chloride ion , (ii) the iodide ion. comment on the difference in their values. M enthalpy change of solution of NaCl(s) = – 2 kJ/ mol enthalpy change of solution of Nal (s) = +2 kJ/mol enthalpy change of hydration of Na+(g) = –390 kJ/mol lattice energy of NaCl = – 772 kJ/mol lattice energy of NaI = –699 kJ/mol.
