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. It is used when the liquids have different boiling point The process of distillation begins with heating a liquid to boiling point. The liquid evaporates, forming a vapor. The vapor is then cooled, usually by passing it through pipes or tubes at a lower temperature. The cooled vapor 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.The key step is to raise the temperature of the mixture to a point above that of the compound with the lower boiling point. But you also have to make sure it's below that of the compound with the higher boiling point. The compound with the lower boiling point will then evaporate, leaving behind the compound with the higher boiling point. If the vapor is then condensed, you're only going to have the compound with the lower boiling point, since you separated the two compounds
