Describe how the process of distillation would be used to remove dissolved impurities from a sample of water |
|
Answer» Answer: Simple distillation works because the dissolved solute has a much higher boiling point than the solvent. When the solution is heated, solvent vapour evaporates from the solution. The GAS moves away and is COOLED and condensed . Dissolved impurities from water can be removed by distillation. Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation, or it may be a partial separation that increases the concentration of selected components in the mixture.
