When BeO is dissolved in water, the hydration energy of its ions is not sufficient to overcome the high lattice energy. +166 kJ/mol AH for Cl(s). NaF NaCl NaBr. Therefore, it is almost insoluble in water. Identify the compounds with the larger lattice energy values Based on the size of the ionic charges, which compounds will have the larger magnitude in lattice energies and which will be smaller? This effect is illustrated in Figure \(\PageIndex{1}\), which shows that lattice energy decreases for the series LiX, NaX, and KX as the radius of X − increases. The lattice energy of BeO is (thermochemical cycle: 4443 kJ mol-1, calculated: 4293 kJ mol-1) and lattice energy of MgO is (thermochemical cycle: 3791 kJ mol-1, calculated: 3795 kJ mol-1) ..
