Hydrated compounds are chemical substances that contain water molecules within their structure. These water molecules are usually integrated into the crystal lattice of the compound, forming what is known as a hydrate. The general formula for a hydrated compound can be represented as \textMX \cdot n\textH_2\textO , where \textMX is the anhydrous compound and n indicates the number of water molecules. When hydrated compounds are heated, they can lose their water content, resulting in an anhydrous form. This process is called dehydration. Common examples of hydrated compounds include copper(II) sulfate pentahydrate ( \textCuSO_4 \cdot 5\textH_2\textO ) and calcium sulfate dihydrate (\( \textCaSO_4 \cdot 2\textH_2\text{
