Distillation!

Evaporation is the process of turning a liquid into a gas by adding heat. When you add heat to the liquid the kinetic energy in the heat makes the particles in the liquid move around faster causing the particles to move farther apart, turning the liquid into a gas. Condensation is the opposite of evaporation, it is the process of turning gas into a liquid by cooling the gas. This is something we can see on our windows as the warm air from inside touches the cold air from outside it creates little drops of water on your windows, this is condensation. 

AIM - To separate a solute from a solvent in a solution using distillation. 

EQUIPMENT - 

Coca-cola, Conical flask, Heatproof mat, a delivery tube and bung, Bunsen burner, Tripod, Gauze mat, Retort stand, Boss head and clamp, Boiling tube. 

METHOD - 

Step 1 - Set up the equipment as shown in the diagram below.
Step 2 - Add approximately 50ml of coke to your conical flask

Step 3 - Light your bunsen burner open the air hole and slowly push the bunsen burner under the tripod. 

Step 4 - Heat the solution until most of the solvent has been evaporated, then turn off your bunsen burner. 

HYPOTHESIS - 

Once the liquid part of coke (water) has been evaporated i think that there will be a sludgy mess left in the bottom of the conical flask, my guess is that this will be the flavoring for the coke and the sugar. 

RESULTS - 
As we turned the orange flame to blue the coke zero inside the conical flask heated up very quickly and was boiling in no time, along with the massive bubbles there was also lots of condensation gathering on the glass. attached to the conical flask was the tube thing wich slowly started pumping small amounts of clear liquid into the test tube that was dumped into a beaker full of ice. Coming out of the test tube was a ongoing stream of smoke. During the 20mins the coke zero slowly went down till there was barely any left, the colour was now almost black kinda like soy sauce but a shade darker. When all the water evaporated from the coke what was left was a small puddle of inky black. 

CONCLUSION -
