Determination of the waters of crystallisation
The water of crystallization in a crystal of any ionic salt can be associated with the size of the cation, magnitude of charge on it, tendency for co-ordination and hydrogen bonds, its lattice structure and other factors involving the anion. Water of crystallization definition is - water of hydration present in many crystallized substances that is usually essential for maintenance of a particular crystal structure water of hydration present in many crystallized substances that is usually essential for maintenance of a particular crystal structure. Experiment : to determine the percentage of water of crystallization in hydrated sodium carbonate (washing soda) water of crystallization is the water which is found as part of the structure of a crystalline substance. Water of crystallization is the number of water molecules, chemically combined in a definite molecular proportion, with the salt in its crystalline state this water is responsible for the geometric shape and colour of the crystals.
