Introduction: Two components of a binary mixture were separated using fractional distillation. A graph showing mL of distillate vs. temperature was drawn and used to identify both components of the mixture. The graph was also used to determine the amounts of each component. The two components were found to be methanol and water. Reactions/Mechanisms/Theory: Boiling point can be used to identify an unknown substance because the boiling point of that unknown liquid can be compared to known boiling points of known liquids. Boiling points can also be used to compare one liquid with another. To find the boiling point of an unknown distillation is used. Fractional distillation is used to determine the boiling point and to separate two different compounds in a mixture. It is used when the components to be separated boil within 25 o C of each other. Each component of the mixture is labeled as a fraction. Fractional distillation works well because it is actually have lots of small distillations occurring in the column. The column is packed with beads on which the distillations occur. A drawing of the fractional set up is shown in figure 1. When the liquid boils, the vapor moves
