Cards in this deck (4)
- 1Filtrationseparates insoluble solids from liquids
separates rock salts - 2evaporationseparate soluble solids from solutions
1. pour the solution into an evaporating disk
2. slowly heat the solution. the solvent will get more consecrated and crystals will form
3. keep heating the dish till you have dry crystals - 3crystallisationseparate soluble solids from solutions
1. pour the solution into an evaporating dish and heat the solution
2. once some of the solvent has evaporated remove the dish and leave the solution to cool
3. the salt should start to form crystals as it becomes insoluble
4. filter the crystals out of the solution and leave them to dry - 4filtration and crystallisation to make rock salts1. grind the mixture to make sure the crystals are small
2. put the mixture in water and stir , the salt will dissolve
3. filter the mixture to get rid of the sand
4. evaporate the water from the salts so only crystals are left
