Question

Water is purified for scientific purposes by distillation. Describe the process.

Answer 1

• It is a process used to separate a pure liquid from a mixture of liquid.
• The process of distillation begins with heating a liquid to boiling point. The liquid evaporates, forming a vapour.
• The vapour is then cooled, usually by passing it through pipes or tubes at a lower temperature.
• The cooled vapour then condenses, forming a distillate. The distillate is a purified form of the original liquid.
• When the liquid evaporates, many impurities are left behind, so they are not present in the distillate.
