2 Ways to Seperate Soluble Solids from Solutions

2 Ways to Seperate Soluble Solids from Solutions

Evaporation

Crystallisation

Pour the solution into an evaporating dish

Slowly heat the solution for the solvent to evaporate and the solution to get more concentrated eventually forming crystals

Keep heating until all you have left are dry crystals

Pour the solution into an evaporating dish and gently heat

Once some of the solvent has evaporated and the solution has become more concentrated or once you see crystals starting to form, remove the dish and eave it to cool

The salt should start to form crystals as it becomes insoluble in the cold, highly concentrated solution

Filter the crystals out of the solution and leave them in a warm place to dry
