Epsom salt, magnesium sulphate, or MgSO4.7H2O comes in different hydrates.

The heptahydrate (.7H2O) comes in as Epsom salt.

It readily loses one water of crystallization, or by gentle heating, to become the hexahydrate, (.6H2O).

When heated to 150 ° C, it further lose water of crystallization to the monohydrate (.H2O)

Finally, when heated to 200 ° C, it becomes anhydrous, i.e. a powder that has no more water of crystallization.

The chemical formula of Epson salt after their gentle heating is MgSO₄.6H₂O.

What is hydrate compounds?

Those compounds in which water molecule is attached with the solid compound is known as hydrated compounds.

Epsom salt is the salt of magnesium metal and one of the hydrated salt, chemically it is represented as MgSO₄.7H₂O. When we heat this salt then dehydration of water molecule from this salt takes place. And at different temperatures, different number of water molecules will release.

At 200°C, all the water of crystallization removes from the salt and we get an anhydrous compound.
At 150°C, 6 water of crystallization releases from the compound and we get a mono hydrated compound.
On the gentle heating only one water molecule releases and we obtain a hexa hydrated compound.

Hence, we get a hexa hydrated Epson salt (MgSO₄.6H₂O)on gentle heating.
