Introduction:
I learned that mixtures and solutions are all 2 substances combined with physical force, but mixtures are heterogenous and solutions are homogenous.
Mixtures are 2 substances combined together with physical force, and solutions are the same, but it is just evenly spread, in another words, it is a homogenous mixture. Homogenous means evenly spread and heterogenous means unevenly spread or distributed. Evaporation is when water turns into gas cause by heat and boiling, while condensation is when gas turns to liquid cause by cooling down. Distillation is the process of separating a mixture using evaporation and condensation.
The process of distillation is that you will boil a mixture or solution like brine, and then the water will evaporate and becomes gas and goes through the tube and enters it, after that, it cools down and it become liquid again. The Salt will then left behind in the conical flask.
Objectives:
Why do you think that we are doing this experiment?
To know how to separate salt and water from brine using distillation.
What are you suppose to learn?
The way of distillation, evaporation and condensation works.
Materials:
2 retort stands and clamps
1 boiling tube
1 rubber bung
1 glass tube
1 conical flask
Bunsen Burner Set
Lead Nitrate
brine
Procedure:
1. Set up the materials
2. boil the brine using the bunsen burner
3. Wait until all the water is in the tube and salt left behind the conical flask
4. To test how pure is the water, put lead nitrate into the water and see if it changes colour to white. (White= not pure)
5. Record down the Results
Observation/ Results:
What happened?
We successfully separate the water and the salt and our water is quite pure and clean. (although there are still some water left behind in the conical flask)
Discussion and Conclusion
What was suppose to happen to the salt water?
Water evaporates and goes to the tube while salt stays still and is left behind in the conical flask.
Was your distillation set up successful? Why or why not?
Yes, because we follow all the instructions carefully and we have great results at last, but not really perfect. :(
How can you improve your distillation set-up?
My partner and I can improve by putting the rubber bung closer to the tube, and can have more pure water.
What was lead nitrate for?
It is for testing how pure is the ditillated water, put a few drops and see if the water turns white, if it turns white, it is not pure enough.
What did you learn with this experiment?
I learnt how to separate the water and salt from brine by using this method, distillation. I also know how to set up the materials for this experiment. I learnt that what lead nitrate is for.
