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).

What is meant by anhydrous AlCl3?
anhydrous means without water and anhydrous AlCl3 means, AlCl3 is hydrated in water therefore anhydrous AlCl3 is used.
What is anhydrous or anhydrous?
anhydrous means if a substance contains NO water it is anhydrous. but if it is hydrated it contains water.
How are hydrated substances usually obtained?
Hydrated substances are formed by water absorption in the anhydrous substance.
Why are common salts called hydrated salts?
Only some salts have hydrates, not all. These salts contain in the formula water of crystallization.

How are anhydrous salts prepared?
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.
When do hydrated salts appear?
When an anhydrous salt retain water in the crystalline structure.
How can anhydrous salt changes into their 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.
MgSO4.7H2O is different from MgSO4?
Mg S O4 . 7 H2 O is a hydrated crystal (Epsom salt - bath salts) 246.47 g/mol (heptahydrate) Mg S O4 is an anhydrous salt 120.415 g/mol (anhydrous)
How many moles are in 7.6 grams of Epsom salts MgSO4?
Depends on if it is hydrated or not. If hydrated, magnesium sulfate heptahydrate, then (7.6g)/(246.47g/mole)=.0308mole. If anhydrous (7.6g)/(120.415g/mole)=0.063mole.

What happens to a colour of a solute molecules when the solvent evaporates or boils?
The color of an anhydrous compound is sometimes different from the hydrated compound.
Are there anhydrous salts in your body?

Chemical formula of anhydrous magnesium nitrate?
It is Mg(NO3)2 when anhydrous and Mg(NO3)2.6H2O when hydrated
