Our topic for today is simple distillation. I need to remove this nail polish. Nail polish can be removed by acid or acetone. Acetone can be obtained by simple distillation, a process of heating a liquid mixture to form vapor and then cooling that vapor to get a liquid. This process is called simple distillation. Distillation is used to purify a liquid by separating the components of a liquid mixture. Now let us do an activity to understand simple distillation. Take a mixture of acetone and water in a distillation flask. Put a thermometer in it and connect the flask to a water condenser. The condenser has cold water running through its jacket to keep the temperature cool. Keep a beaker at the outlet of the condenser. Heat the mixture, keeping an eye on the thermometer. When the temperature hits 56 degrees Celsius, acetone starts to vaporize. These vapors condense in the water condenser and the condensed acetone gets collected in the beaker. When all the acetone vaporizes, water is left in the flask, while acetone is collected in the beaker. In this way, acetone in water gets separated by simple distillation. The boiling point of water is 100 degrees Celsius, while the boiling point of acetone is 56 degrees Celsius. Due to the sufficient difference between their boiling points, these components can be separated by simple distillation. However, simple distillation does not work properly when the difference between the two boiling points is less than 25 degrees Celsius. This is because the components do not get separated and purified completely. If we repeat this process multiple times, we will be able to separate these two components. However, this is very time-consuming. That's why a special type of distillation called fractional distillation is used.
