What is the difference between water on hydrate crystals vs hydrate water?

Answer 1

Moisture water is nothing but adsorbed water molecules from surrounding environment. One can simply remove it by increasing temperature of the sample.

Water of crystallization and hydration both are same. They are necessary to from the crystal of the compound. The water molecules required to from a crystal are considered while calculating the molecular weight of the compound. The compound which has water molecules or water for crystallization is called as hydrate form of the compound. one single compound can be available in hydrate and unhydrous form. For example: sodium tartrate Molecular formulaC4H4Na2O6 (anhydrous)

C4H4Na2O6. 2H2O(dihydrate)Molar mass194.051 g/mol (anhydrous)

230.082 g/mol (dihydrate)

Answer 2

water of crystallization is the moles of water within the crystal i.e. amount of water surrounds the molecule that forms the crystal..... water of hydration refers only to the fact that water is within the crystals

Answer 3

Both precipitation and crystallization require a supersaturated solution to form. The major difference is that crystallization forms crystalline solids, and precipitation forms an amorphous solid.

Answer 4

Look, if you have some water on the surface of a crystal, hydrate or no
hydrate,
this water is just staying there, with no chemical relation with the crystal
molecules and eventually will evaporate easily because the only force
mantaining it there is some surface tension coming from the crystal
surface itself.
By other hand in hydrates the water molecules are chemically bonded
with the crystal molecules and cannot, for example, evaporate.
