A textbook on chemical thermodynamics states, “The heat of solution represents the difference between the lattice energy of the crystalline solid and the solvation energy of the gaseous ions.” (a) Draw a simple energy diagram to illustrate this statement. (b) A salt such as NaBr is insoluble in most polar nonaqueous solvents such as acetonitrile (CH 3 CN) or nitromethane (CH 3 NO 2 ), but salts of large cations, such as tetramethylammonium bromide [(CH 3 ) 4 NBr], are generally more soluble. Use the thermochemical cycle you drew in part (a) and the factors that determine the lattice energy (Section 8.2) to explain this fact.
