What is Water of Hydration?</h3>
- In chemistry, water molecules found inside crystals are referred to as "water of crystallization" or "water of hydration." When crystals are formed from aqueous solutions, water is frequently included.
- The entire mass of water in a substance at a specific temperature is sometimes referred to as water of hydration, and it is typically present in a stoichiometric ratio.
- The term "water of crystallization" has historically been used to describe water that is not physically linked to the metal cation but is present in the crystalline structure of a metal complex or salt.
- Many chemicals include water molecules in their crystalline structures when they crystallize from water or solvents that contain water. Heating a sample usually removes the water of crystallization, but the crystalline qualities are frequently lost.
Given that hydrate is 10.8% by mass
molar mass = 499.52 g/mol
calculating the amount of water
mass of water = 
mass of water = 53.95 g
moles of water = 
moles of water =
= 3
then the water of hydration x in narceine. xH₂O is 3

The three subatomic particles are proton, neutron and electron. Proton and neutron are present inside the nucleus where as the electrons are present revolving in the orbits around the nucleus. Isotopes of the same element have same atomic number but different number of neutrons. Similarly, ions of an element have different number of electrons. For example, neutral Ag atom has 47 electrons, where as
ion has 46 electrons. Atomic number which is the number of protons is unique for an element. So the number of protons would remain same for different atoms of same element Ag.
