WebE.g. hydrated copper(II) sulfate is CuSO 4 ∙5H 2 O; A compound which doesn’t contain water of crystallisation is called an anhydrous compound . E.g. anhydrous copper(II) sulfate is CuSO 4; A compound can be hydrated to different degrees. E.g. cobalt(II) chloride can be hydrated by six or two water molecules; CoCl 2 ∙6H 2 O or CoCl 2 ∙2H 2 O WebIt can be considered as enthalpy of solvation with the solvent being water. Hydration enthalpy is also called hydration energy and its values are always negative. For a chemical reaction, M +(g) + aq → M +(aq) Enthalpy change = ∆H Hyd. Water is considered to be a polar solvent because it has a positive (H atom) and negative (O atom) poles.
WebThe conversion of anhydrous compounds to hydrated compounds is reversible by heating the hydrated salt: Hydrated : CuSO4•5H2O ⇌ CuSO4 + 5H2O :Anhydrous. The degree of hydration can be calculated from experimental results: The mass of the hydrated salt must be measured before heating. The salt is then heated until it reaches a constant mass.
