Crystallization method bbc bitesize

WebCrystallisation is a separation technique that is used to separate a solid that has dissolved in a liquid and made a solution. The solution is warmed in an open container, allowing the solvent to evaporate, leaving a saturated solution. A solution that has as much solid dissolved in it as it can possibly contain is called a saturated solution. WebOct 5, 2024 · Stir to dissolve the salt. Place the filter paper in the mouth of the funnel. Place the evaporating dish under the funnel to collect the liquid. Slowly pour the rock salt solution into the funnel. Make sure you don't over-fill the funnel. You don't want the liquid to flow around the top of the filter paper because then it isn't getting filtered.
