if you mean epsom salts (magnesium sulfate) then heating it will result in a decomposition reaction, where magnesium oxide (s) and sulfur trioxide (g) is formed. The decomposition reaction is therefore a chemical change.

Is H2O an anhydrous compound?

The term anhydrous means, does not contain water. H2O is the chemical formula for water. Hence, it is the opposite of anhydrous. It is the most hydrous of all substances.


What is the difference between a hydrous compound and an anhydrous?

A hydrous compound contains water molecules in its crystal structure, while an anhydrous compound does not contain any water molecules. Hydrous compounds can lose water when heated, converting into an anhydrous form.


What are a few examples of anhydrous crystals?

Anhydrous copper sulphate is a paler blue compared to hydrous copper sulphate. See the related link for further information.


What is the reaction CuSO4 5H2o plus heat?

CuSO4 * 5H2O ----> CuSO4 + 5H2O. This is true because CuSO4 * 5 H2O is a salt weakly bounded to water, that is why it is hydrous. When it decomposes, the weak bonds are broken making the products above. CuSO4*5H2O formula is [Cu(OH2)4]SO4*H2O CuSO4 + 5H2O --> [Cu(OH2)4]SO4*H2O


What is an hydrous salt?

An hydrous salt is a salt that contains water molecules within its crystal structure. These water molecules are known as "water of hydration" and can be removed through heating to form an anhydrous salt.


What colour does hydrous copper sulphate turn when heated?

Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.


What is another word for containing water chemically?

If you mean a compound containing water, the term would be hydrous or hydride, the same material without water would be "anhydrous" or "anhydride" Hope that helps
