hydraattina
Hydraattina refers to a substance that has incorporated water molecules into its crystal structure. This phenomenon is common in ionic compounds, where water molecules can bind to the ions through coordinate covalent bonds or hydrogen bonding. The presence of these water molecules is indicated by the term "hydrate" in the chemical name or formula. For example, copper sulfate can exist as anhydrous copper sulfate (CuSO4) or as copper sulfate pentahydrate (CuSO4·5H2O), where "pentahydrate" signifies the presence of five water molecules per formula unit of copper sulfate.
The number of water molecules associated with a compound is specific and often denoted by a prefix
Heating a hydrate usually causes it to lose its water molecules, reverting to the anhydrous form. This
