Separating Mixtures | SL IB Chemistry Revision Notes 2025
Crystallisation. Used to separate a dissolved solid from a solution, when the solid is more soluble in hot solvent than in cold (e.g. copper sulphate from a solution of copper (II) sulphate in water); The solution is heated, allowing the solvent to evaporate and leaving a saturated solution behind; You can test if the solution is saturated by dipping a clean, dry, cold glass rod into the solution

Step 2. Pulling out the Iron Filings. In this step we used a magnet wrapped in gladwrap to separate the Iron Filings from the salt and sand. We covered the magnet with gladwrap because the Iron sticks to the magnets very strongly. As you can see in the picture when we lowered the magnet into the mixture and all of the Iron came out.
