EXP 5: Distillation

Distillation

Process used to recover a liquid from a dissolved non-volatile impurity by heating the liquid so it becomes a vapor, which is then condensed into liquid form by cooling

Boiling point

Used as an index of purity in this experiment

Substance that evaporates readily or one that has measurable vapor pressure

Definition of volatile

Red-Colored Alcoholic Solution or Impure ethyl alcohol (CH3CH2OH)

120 cc of what was placed in the distilling flask

40 drops

How many drops were counted before changing the receiving flask?

To avoid high pressure that would cause explosion of the flask

Why shouldn’t the receiver be fastened to the condenser with a tightly fitted cork?

Distillate; Ethyl Alcohol (CH3CH2OH)

General name and compound name/formula of purified substance in the receiving flasks

Flammability Test

How was the presence of purified CH3CH2OH validated?
