Separating a Mixture using Distillation

Kia ora, today we are doing a condensation experiment in chemicals.

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, clamp, coke zero, beaker and boiling tube.

Coke Zero ingredients

Method:             

1. Set up equipment as shown in the diagram.

2. Add approximately 50 mL of saltwater to your conical flask.

3. Light your Bunsen burner. Open the air hole and gently push the Bunsen burner under the tripod.

4. Heat the solution until most of the solvent has been evaporated. Turn of your Bunsen burner.

Hypothesis: 

I think that the Coke Zero will be dark and will leave behind a little bit of sugar when we are done.

I think that the Cocoa-Cola will leave more sugar behind and will be a lighter colour.

First off the condensation began in the flask and then started to boil which caused it to evaporate. The reason it started to boil is because we heated the flask up with the element. As this was happening the solvent started to evaporate into the beaker.Our outcome was very interesting, The coke zero left behind a strange sugar like substance in the flask and the beaker got filled up with water.
In conclusion I was slightly right with my hypothesis apart from the sugar part.
