Question

12 (a). Name the process you would use for the following: purification of sea water

Answer 1

• The process used for the purification of seawater is Simple distillation.
• Simple distillation is used to separate a solvent from a solution.
• Simple distillation is the method used to separate substances in mixtures at significantly different boiling points.
• This method works because water has a much lower boiling point than salt.
• When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container and we get pure water.
