Filtration: Solid + Liquid >
Evaporation: Liquid ( solid dissolved in liquid) > gas > solid
Distillation: Liquid ( solid dissolved in liquid) > gas > liquid solid
What is :
Evaporation: heating liquid, turns to a gas so we can separate a solution, by evaporating away the solvent to leave a solute (solid).
Condensation: cooling down a gas, turn into a liquid it is a reverse of evaporation where liquid water becomes a vapour.
Aim: To separate a solute from a solvent in a solution using distillation.
Equipment: A solution of saltwater, conical flask, heatproof mat, a delivery tube and bung, Bunsen burner, tripod, gauze mat, retort stand, boss head, and clamp, boiling tube
Method:
- Set up equipment as shown in the diagram.
- Add approximately 50 ml of saltwater to your conical flask.
- Light your Bunsen burner. Open the air hole and gently push the Bunsen burner under tripod.
- Heat the solution until most of the solvent has been evaporated. Turn off your Bunsen burner.
Notes:
- So for the first few minutes there were small bubbles that would occur a few times.
- After awhile the coke started to evaporate.
- The gas started to condensation and turned into liquid.
- Now the coke is changing from coke to water the more the liquid starts evaporate because after the gas starts to condensation and turn into liquid.
- After it is all finish there is only a thick layer of sugar that is black, there are also some of the colour and adaptive.
