Is the dehydration and hydration of CuSO4 5h2o reversible?
Subsequently, one may also ask, is dehydration of a hydrate reversible?
The water molecules in a hydrate crystal can be removed by heating. In this dehydration reaction the crystal structure of the solid will change slightly and the color of the solid salt may also change. Decomposition is irreversible dehydration.
Similarly, why is CuSO4 5h2o considered a hydrate? The reason that CuSO4. 5H20 is considered a 'Hydrate', or more accurately a 'pentahydrate' is due to these water molecules that are integrated into the crsytals in the hydrated form.
In respect to this, is the dehydration of CuSO4 5h2o a physical or chemical change?
Dehydration of hydrates is considered to be a chemical change. The water molecules are trapped in the crystal structure of the copper ii sulphate, and there are always five of them per formula unit; this gives the compound a reliable formula, and allows stoichiometric calculations to be made.
How do you separate water from a hydrate?
Experimentally measuring the percent water in a hydrate involves first heating a known mass of the hydrate to remove the waters of hydration and then measuring the mass of the anhydrate remaining.
