Fractional distillation is a method for separating liquids with different boiling points.
For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points. When the mixture is heated, one liquid evaporates before the other.
In this experiment, we will use fractional distillation to separate a mixture of ethanol and water.
The boiling point of ethanol is 78°C and the boiling point of water is 100°C.
