Here is the formula for hydrated copper(II) sulfate. Notice that water of crystallisation is separated from the main formula by a dot.

Moreover recovering useable water from supersaturated brines generated as reject streams from RO/NF process can improve overall process efficiency. Therefore a good understanding of crystallization ...

In their research, they chose three chemically versatile organic compounds to grow "elastic organic crystals." From there, they tested how each of these materials interacted with airborne water ...
