What is the purpose of the distillation technique? What is the difference between simple and fractional distillation?
Distillation = purification technique that separates substances in a mixture based on boiling point
Simple = evaporation-condensation process is carried out once
Fractional = evaporation-condensation process is carried out multiple times
