Destillation

Hi, welcome to my blog again last week we did the evaporation experiment and now we are doing distillation experiment and taking photos and information and put it on my blog.

Aim: To separate a solute from a solvent in a solution using distillation.

    

Hypothesis:  I think the coke zero will be dark and leave no sugar.

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 50 mL of saltwater to your conical flask.

 3. Light your Bunes 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 off your Bunsen burner.

Result:

 The result  Is the coke zero was not kind of dark but my thinking in the hypothesis that it will leave no sugar but there is like a little bit of sugar there but not many and the solvent was clear when you look at it.

Discussion:  

In the tube inside on it, it's solvent, the solvent is started evaporating, the bowl started boiling when you heat it up the zero coke started boiling and the solvent started evaporating then after all done the solvent was clear like water and no like any colour something inside the stopper. Inside the flask was like no water but there is little bit of water left and same as sugar and the colour of the coke zero is dark black with a little bit of brown.

Conclusion:

So first we did is put the coke zero in the flask then we put it on the element then like suddenly the coke zero was boiling it up and then we take a picture on it so we can blog it on our blog then we went to the lunch and comeback in period 5 then we come back here our teacher did and Finnish it off our work and then we take a picture the coke zero is like the colour is dark black with kind of brown and there is sugar leftover same as water.
