Define water of crystallization. Give the chemical formula for two compounds as examples. How can it be proved that the water of crystallization makes a differences in the state and colour of the compounds?
Answers
Water of crystallization is the fixed number of water molecules present in one formula unit of a salt. Or we can say water stoichiometrically bound into crystal. For example, chemical formula of hydrated copper sulphate is CuSO4 · 5H2O. ... Curd and other sour substances contain acids.
Explanation:
In chemistry, water(s) of crystallization or water(s) of hydration are water molecules that are present inside crystals. ... Classically, "water of crystallization" refers to water that is found in the crystalline framework of a metal complex or a salt, which is not directly bonded to the metal cation.
Water of crystallization is the fixed number of water molecules present in one formula unit of a salt. ... For example, chemical formula of hydrated copper sulphate is CuSO4 · 5H2O. Copper sulphate has 5 molecules of water of crystallisation.
when we remove water of crystallisation,the water molecules present in the compound get removed and we are left with what is called the dehydrated form of that compound
for eg. when water of crys. is removed from Cu,it changes its color from blue to
