1 Calculate the enthalpy of solution of
NaClgiven that the lattice enthalpy of formation of
NaClis -771
kJmol^(-1)and the enthalpies of hydration of sodium and chloride ions are -406 and
-364kJmol^(-1)respectively. 2 Calculate the enthalpy of hydration of bromide ions given that the hydration enthalpy of barium ions is
-1360kJmol^(-1), the lattice enthalpy of formation for
BaBr_(2)is
-1937kJmol^(-1)and the enthalpy of solution of
BaBr_(2)=-38kJmol^(-1). 3 Calculate the lattice enthalpy of formation of calcium iodide given that its enthalpy of solution is -120
kJmol^(-1)and the enthalpies of hydration of calcium and iodide ions are -1650 and
