Step 1

Hydrated salts have water within their crystals when the crystals are formed from water; an anhydrous salt is where the crystal has had the water driven out.

Step 2

It is important to heat the hydrate for a sufficient amount of time to ensure that all of the water evaporates to get an accurate recording of how much water was in ...
