This method evaporates water from the solution but then cools it and condenses it into a separate container.
example: salty water
vapor to fall, causing the gas to turn into liquid again.
It consists of evaporating a liquid and turning it into a gas due to an increase in temperature and/or pressure
It is a chemical solid–liquid separation technique, in which mass transfers from the liquid solution to a pure solid crystalline phase
example: salt dissolved in water
example: copper sulphate
1. Pour 100mL of distilled water into a beaker
2. Place the beaker on a tripod and heat to 26 grades
3. Add the copper sulfate until it does not dissolve any more and stir continuously
4. Pour the saturated solution into the glass Petri Dish
5. Leave it for some days
1: pour the solution in the evaporating basin
2: put the basin on a tripod
3: light a Bunsen burner and place it under the tripod
4: wait a few minutes and observe the result. Little crystals of salt will be formed and will remain at the
bottom of the basin
