Hydration energy and lattice energy
Web1 jun. 2024 · In salts for which the hydration energy is higher than the lattice energy, solvation occurs with a release of energy in the form of heat. For instance, CaCl2 (anhydrous calcium chloride) heats the water when dissolving. However, the hexahydrate, CaCl2·6H2O cools the water upon dissolution. Web2 dagen geleden · Therefore, subambient variable-temperature SCXRD (VT-SCXRD) studies were carried out, initially using a cryostat that used dry N 2 gas at 1 bar. Under these conditions, the hydrous crystals still ...
