WebThe Hydration Shell of Ions. Ions in solutions are not free. Each is surrounded by a shell of water molecules, called a hydration shell, held by the attraction of the water dipoles to the charged ion.For cations, the oxygen end of water dipoles point toward the center of a cation, maximizing the ion-dipole interaction. WebType A hydrates can reach phase change temperatures up to 12.5°C whereas the highest phase change temperature for type B hydrates is approximately 10°C. PCM, Phase change material.
