Hydrated salt-Salt with water of crystallization are called hydrated salt. Those water are bonded with dative bonds though.
Anhydrous salt-Salt which have lost their water of crystallization are called anhydrous salt.
To obtain hydrated salt, you can dissolve an anhydrous salt in water and then evaporate the water to grow hydrated crystals. Alternatively, you can mix the anhydrous salt with a calculated amount of water to form a solution with a specific hydration level.
cobalt chlorideCompound that exists in two forms: the hydrated salt (CoCl2.6H2O), which is pink, and the anhydrous salt, which is blue. The anhydrous form is used as an indicator because it turns pink if water is present. When the hydrated salt is gently heated the blue anhydrous salt is reformedcobalt chlorideCompound that exists in two forms: the hydrated salt (CoCl2.6H2O), which is pink, and the anhydrous salt, which is blue.

The final mass of anhydrous cupric sulfate will be less than the initial mass of hydrated cupric sulfate due to the loss of water during the dehydration process. The final mass can be determined by subtracting the mass of the water lost from the initial mass of the hydrated salt.
For example uranyl nitrate may exist as an anhydrous compound.
Anhydrous sodium sulfate is a desiccant, meaning it has a strong affinity for water. When added to a dichloromethane solution, the anhydrous sodium sulfate will absorb any water present, effectively removing it from the solution by forming a hydrated salt. The water-free dichloromethane can then be decanted or filtered off for further use.

When an anhydrous salt retain water in the crystalline structure.
A hydrated salt has a number of waters of hydration combined to each molecule of salt whereas an anhydrous salt is one that has had its waters of hydration removed. An example of a hydrated salt is nickel sulfate hexahydrate, NiSO4·6H2O. The waters of hydration can be removed by a simple heating, resulting in NiSO4(s) + 6H2O(g).
The chemical formula for anhydrous salt is the same as the formula for the hydrated version of the salt, but it does not include water molecules. For example, anhydrous copper sulfate is CuSO4, while hydrated copper sulfate is CuSO4·5H2O.
If the original sample is unknowingly contaminated with a second anhydrous salt, the reported percent water in the hydrated salt will be too low. This is because the presence of the anhydrous salt will increase the overall weight of the sample without contributing to the water content calculation, leading to a lower reported percentage of water in the hydrated salt.
On heating, hydrated salts lose their water of crystallization and as a result, the crystals lose their shape and colour and change to a powdery substance.
Anhydrous salts prepared by evaporating the water contained in a hydrated salt. However, anhydrous salts are non-electrolytes, meaning they can't pass an electric current.
Anhydrous is the term for a hydrate with water heated off. when a hydrated salt is heated, it loses water of crystallization leaving an anhydrous salt.
This depends on: - if it is an anhydrous or hydrated salt - if it is a salt of Cu(I) or Cu(II) For CuSO4(anh.) the answer is 0,00364 moles.
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.
Anhydrous simply means 'without water'. The opposite is a hydrated substance, in which salt crystals contain water as an integral part of the crystal. For example, anhydrous cobalt(II) chloride, CoCl2, is a blue powder. Add water and you form cobalt(II) chloride hexahydrate, CoCl2.6H2O, which is a pink colour. Anhydrous cobalt chloride can be used to test for the presence of water because of this dramatic colour change. In addition, hydrated copper(II) sulfate, CuSO4.5H2O, forms bright blue crystals. Heating them drives off the water of crystallisation and anhydrous CuSO4, a grey/white powder, is formed. Adding water will reform a blue solution of the hydrated salt.
