Rsc water of crystallisation
WebJan 25, 2024 · The crystallisation process is used to obtain a pure solid substance from an impure sample. This is accomplished as follows: A solution is formed by dissolving the impure solid substance in the minimum amount of water to form a solution. To remove insoluble contaminants, the solution is filtered.

WebWater of crystallization: The number of water molecules present in one formula unit of a salt is known as the water of crystallization. For example, in hydrated Copper sulfate ( CuSO 4 · 5 H 2 O ), 5 water molecules are present. So, the water of crystallization is 5 in this hydrated species.
