Explain how distilled water is obtained.
2 flasks - condenser - connecting tubes - salt water solution - flame - stoppers
Place the condenser horizontally on the stand
Place the flasks, one over a Bunsen flame and the other on a lab bench
Pour the salty water into the flask that has been placed on top of the flame
Place the stoppers in the two flasks
Connect the two flasks to the condenser using the couplings
Connect the water hose to the condenser and faucet and the other to the condenser and strainer
Open a Bunsen flame, turn on the water tap, and see what happens
We notice the evaporation of water and the appearance of points of fresh water in the other flask.
Because of the different boiling points of both water and salt, water has a low boiling point. It will first boil and turn into gas and leave the flask. Then the water vapor will condense in the cooling tube and flow into another flask. At this point, the two parts of the solution will be completely separated.
