WebSep 7, 2024 · What is water of crystallisation GCSE? A solid which is hydrated contains ‘water of crystallisation’. This is water which is ‘chemically combined’ in the crystal structure. If we heat a hydrated solid gently, the water will be released and the solid will lose mass. In this experiment you will heat hydrated iron(II) sulfate crystals.
