Hurumanu - Evaporation, Condensation, Distillation...

Introduction: Today we did an experiment on Distillation, Evaporation, and Condensation, and it was also a really good day...

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

Equipment: Solution Of Coke, Conical Flask, Heat Proof Mat, Delivery tube, Bunsen burner, Tripod, Gauze Mat, Bosshead & Clamp, Boiling tube, Retort stand.

Method:
1. A mixture of coke and water was heated in a conical flask…
2. The water evaporates leaving the coke behind…
3. The water vapor flows through the delivery tube…
4. Heat the solution until most of the solvent has been evaporated. Turn off your element…

Results: We saw that the coke started to bubble because of the heat of the element, then at the end of the experiment there was syrup at the bottom.

Discussion: What or how we did for this experiment... We used a Conical Flask to hold our Solution Of Coke, then we boiled it with an element we then evaporated the Coke, and we got vapor out of it, then we used a delivery tube to get the vapor to travel into a boiling tube because the delivery tube was connected to a conical flask and a boiling tube, we then used Condensation, we got ice and put it in a beaker and put it just below the boiling tube, to cool it down, the coke then turned into a syrup-like substance, it as the leftover sugar from the coke, The boiling tube was then filled with water from the vapor...

Conclusion: Did it work? In conclusion, it did work and we ended up with a dark like syrup on the bottom of the Conical Flask...

Hurumanu - Evaporation Experiment - 2020

Introduction: We have been learning about
Evaporation is... It is when a liquid is turned into a gas.

Aim: The aim is to Evaporate Copper Sulfate- (blue liquid)...
To separate the mixture...

Solute? Solvent? Solution? Mixture...

Hypothesis: I think what will happen is the (Blue Liquid) in the Copper Sulfate will somewhat disappear a little, there will probably...

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 it on the element...
3. Add Copper Sulfate to the evaporating basin until it is quarter full...
4. Carefully place the evaporating basin on top of the beaker...
5. Turn on the Element to 2, maybe in a while bumping the element up to 6...
6. Heat the Solution until most of the Solvent ha been evaporated and crystals of solute forming...
7. Turn off the element- be careful of the beaker, it will be hot for a while...

Observation: As time goes by we see that inside the beaker there where bubbles forming, and maybe a few drops of water & you can slightly hear the small bubbles popping or the sound of boiling happening...

Conclusion: In conclusion, our experiment did not work, but we think we have an idea for the next time around...

Evaluation: It was fun but, it didn't go as planned but now we see that we may need to adjust some things next time around...

Hurumanu - Dilution Experiment...

For science this week I or my group did an experiment on Dilution -(Meaning: Making a liquid less concentrated or weaker)
We did this dilution experiment because or to explain or learn how dilution works, we were doing something or using a method called Serial Dilution...
It means we repeated this process for a while...

Aim: To make a dilution series to investigate concentration...

Equipment: A Potassium Permanganate crystal, Six large text tubes, Tweezers, A plastic transfer pipette, A test tube rack, 10ml measuring cylinder, Spatula...

Method: 
1. Place the six test tubes in the test tube rack, Label the rack with numbers 1-6
2. Using the measuring cylinder, fill test tubes 1 with 10ml of water, fill the other test tubes with 5ml of water.
3. Using your tweezers, add a single crystal of potassium permanganate to test tube 1.
4. Gently shake the test tube until the crystal has dissolved.
5. Using the transfer pipette, carefully remove 5ml from test tube 1 and pour it into test tube 2.
6. Rinse the transfer pipette thoroughly to ensure that no purple solution remains.
7. Gently shake test tube 2 and repeat the transfer process, transferring exactly 5ml of the solution to test tube 2 to test tube 3.
8. Rinse the pipette again and repeat the transfer process for test tube 4, 5, & 6
