Distilation

Distillation Experiment

 Today in Chemicals science we did an experiment on distillation.
Separating a mixture using Distillation
Aim: To separate a solute from a solvent in a solution using distillation.
Hypothesis : I think that the Coca-Cola will stay the same, and Zero will change. 
Equipment: A solution of different types of cokes, 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 coke to your conical flask. 
3. Start the element.
4. Heat the solution until most of the solvent has been evaporated. Turn off the element.  

First we set up the equipment we needed. Our group had the Coca-Cola Zero. 

Observation: First the Coke was still and it was just heating up, then it just started to form some little bubbles, it then started to bubble up a lot,  it looked like clear water was being sucked by the delivering tube into the flask. 

Discussion: In the conical flask that had the coke in it, at the bottom there were some sugar left When we heated the Coca-Cola, it evaporated and it got trapped which separated it,  we used ice to cool it down.Our flask had less sugar left over compared to the other group that had the original Coca-Cola that had sugar in it.

But then there was a clear liquid that has been sucked by the delivering tube and I think that it the condensation from the Coca-Cola, I guess there's only one way to find that out, is to look on the ingredients on the Coca Cola bottle. 

Conclusion: This experiment was very interesting but the results were a little shocking,  because I've always thought that the Zero Coca-cola had no sugar in it because it say on the label of the bottle, then doing this experiment shows that there was actually a decent amount of sugar left at the bottom of the flask. 

VIA Test

These are the results of my personality VIA test.

1.I think that this is a skill of mine, I manage to be grateful for everything I have because I know I have alot more than some other people and that I am a very lucky person,
2. I'm not sure why curiosity is my second skill, I cam a very curious person but I would have thought some of my other skills would come before it.
3.I am a kind person most of the time and when im not its either because they have done something or Its banter with friends and frankly if I was going to be kind to my friends it wouldn't go down so well.
4. I guess this one fits, I'm not sure.
5. This is very true, I use humour in every situation possible. When I'm sad, when someone else is, when its an awkward situation or just in everyday conversation.

Evaporation

We have been learning  about evaporation, what evaporation means is when a liquid of some sort by which water changes from a liquid to a gas or vapour. Evaporation is the primary pathway water moves from the liquid state back into the water cycle as atmospheric water vapour.

Aim: Evaporate copper sulfate ( blue liquid) = Solution.

Hypothesis: Gas formed, something will be left behind, 

Equipment: Copper sulfate solution, 250mL Beaker, heat proof mat, evaporating basin, element. 

Method: 

1. Set up element

2. Add 100mL of hot water to the beaker and place on the element.

3. Add copper sulfate to the evaporating basin until it is quarter full.

4. Carefully, place the the evaporating basin on top of the beaker. 

5. Turn on the element to 4.

6. Heat the solution until most of the solvent has been evaporated and crystals of solute are forming. 

7. Turn off the element- careful not to touch as will be hot for a long time.

Oberservations: It slowly started to heat up, there was steam, started to make a powder.

Conclusion: Yes.

Discussion: What happened and why… using your scientific keywords (Evaporating, Solvent, solute, solution, mixture, heat, boil)

Evaluation: This was fun but next time I would only have one thing on the element at a time to make sure it boiled.

Dilution expierament.

Intro: we were learning about dilution, we had to dilute potassium permanganate with water.

Aim: To dilute potassium permanganate to see how dilution works.

Method: we had to put 10 mls of water in the first test tube then a little bit of potassium permanganate.

Then we had to take 5 mils of that and add it to the 5 mls of water in the next test tube then do the same until it got to the end and it was barely coloured anymore.

Equipment: 

1.potassium permanganate.

2. water.

3. test tubes and racks.

4. Pipette.

Results:

Discussion: They slowly got lighter and more dilute, you could clearly see the colour change. 

P.E Jump Jam/ Just Dance.

This week in p.e we have been working on getting active in a fun way, so we get to choose what we are doing this week we have done, just dance and jump jam.

For jump jam we only did it for about 30 odd minutes and it was fun but eventually it got boring so we went back to just dance, all we have been doing is dancing and having fun with it but I have genuinely enjoyed P.E lately. 

We are in groups that we choose so I am with a group of friends and I like having it set up that way, I find it harder to have fun if I am with people who I don't consider friends.
happy


For just dance  we just put on some of the videos and tried to dance the way the people on the screen did. We did this for just under an hour each lesson so it was a good amount of fitness.

Filtration Experiment

We are doing an experiment to separate two chemicals from a mixture that we make.

Aim: To separate a solution from a precipitate ( Precipitate is the name for a solid that forms into a liquid during a chemical reaction.

Hypothesis: I think that the small particles will pass through the filter and the larger particles won't.

Method: 

1. Pour approximately 50 ml of copper sulphate solution into a beaker.

2. Add the same volume of sodium carbonate solution. A reaction will happen, you should see a cloudy blue precipitate form. Called copper carbonate. 

3. Watch demo then fold filter paper to fit inside the funnel

4. Place the funnel with the filter paper inside of it, into the mouth of a conical flask. 

5. Stir the mixture in the beaker, then carefully pour it into the funnel. 

6. Observe what happened.

Equipment:
Copper sulphate
Conical flask
Stiring rod
200ml beaker
Funnel
Filter paper

Observations:
when the two chemicals mixed it turned blue and bubbled
then when ot went through the filter paper it was completely clear.
