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)
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
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.
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.

The difference between the hydrate and the anhydrate is 0.624g. Dividing this by the total hydrate mass gives you 0.624/1.632=0.382, which is about 38.2%.
Whenever talking about a molecule of water, there is ALWAYS two atoms of Hydrogen and one atom of Oxygen. In a hydrate, water is part of the crystals. When a hydrate is heated, the composition of it is changed, because water is released. And as soon as the composition is changed, it is a new substance with new properties.
Hydrated salt-Salt with water of crystallization are called hydrated salt. Those water are bonded with dative bonds though.Anhydrous salt-Salt which have lost their water of crystallization are called anhydrous salt.
the water can be removed heating the anhydrous.
The answer is 10 moles water.
de-hydrate
I don't know but i'm smart

Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
Calcium chloride easily absorb water, it is hygroscopic.

yes you can u could say u need water to hydrate
hydrateA solid compound that contains water molecules is called a hydrate. The stability of a hydrate depends on the nature, temperature, and relative humidity of the compounds.
