Distillation Experiment

 Today we are doing a distillation experiment:

What evaporation is: evaporation is when a liquid is heated up and turning to gas by gaining energy and moving faster.

What is condensing: When a gas cools down and losses energy and then starts to become a liquid from the particles moving closer together.

Aim: To separate a solution (coke/coke zero) to form a solid and a liquid.

Hypothesis: We are going to end up with both solid and liquid. The solid is going to have all the color from the drink and the liquid will be clear because the solid is taken out.  I think that both liquids will be the same for both drinks because it will lose the solids added to both of them. In the regular coke I think the sugar will stay as a solid while most of the other products in the solution will be a liquid. In the coke zero I think instead of sugar thee sweetener will stay solid.

Equipment: Bunsen burner, coke/coke zero, flask, tripod, heat mat, beaker

Method: 

1. Set up the equipment

2. add 50mls of your liquid to a flask

3. Light your Bunsen burner open your air hole and put under the tripod.

4. heat up until most of the solvent has been evaporated. Turn off Bunsen burner.

Observation: 

The coke boiled under the heat and the liquid evaporated. We caught the liquid and it was clear while the solid stayed in the flask. The solid that was left was sugar. The sugar in the coke zero was like a small brown sludge like the regular coke but looked at look more like dust.

Conclusion:

My hypothesis was correct at the liquid went clear and the sweetener stayed solid. The heat made the drink to boil then we found a way to catch the evaporated liquid so that we now had to things separate apart from each other. The liquid evaporated and the when the solid stayed into the flask. The coke had more sugar because their was more solids compared to coke zero. The liquid we catch by condensing the steam and cooling it back down again.

BYE!
