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:
1 - Set up the equipment as shown in the diagram
2 - Add approximately 50mL of saltwater to your conical flask
3 - Light your Bunsen burner. Open the air hole and gently push the Bunsen under the tripod
4 - Heat the solution until most of the solvent has been evaporated. Turn off your Bunsen burner
Hypothesis: I think that the color of the zero coke will change.
Results ( Observation) - After a while, I could see it bubbling, and the coke was turning into clear liquid and was going through the delivery tube.
Discussion : First we had a solution which was the coke, because of the heat it started bubbling, and we saw steam going up which meant it was evaporating, and the solution started going through the delivery tube, then it turned into clear liquid, which meant it was condensed.
Conclusion: The solution turned into a solvent, which was clear liquid, it changed to colorist, which means it the solution started off black and then the color changed to white.
