When there is no more solute can be dissolved in a solution, a saturated solution is obtained. When a hot saturation solution is cooled down the solute will come out in solid form as a crystal. Small crystals will be found in fast cooling. If we hang a small crystal in a h ot saturated solution it will grow bigger when it cools slowly.

some solid solute.
No,it's a physical change Because there is no change in matter's composition.
Yes: for example destillation, crystallisation, freezing .....
Only some salts have hydrates, not all. These salts contain in the formula water of crystallization.
- salts are ionic compounds - salts are products of neutralization reactions
No, only some salts change the color after dehydration.
The change of color after dehydration is not a general phenomenon.
what can form deep insides earths crust by crystallisation of melted materials
H
Yes it is.
It is a Physical Change
Yes. There is no water of crystallisation.
This can be done by heating the salt.
NaCl salt does not contain water of crystallization.
Crystallisation
Various salts are added to the mix:Copper salts - blueStrontium salts - redSodium salts - yellowBarium salts - greenCalcium salts - orangeCobalt salts - blueCryolite - yellowLithium salts - bright red
The water of crystallization is a type of water contained in the molecular structure of a compound.
