Ben put 100 ml of water and 100 ml of oil in a beaker then he stirred the mixture. Which is the best way to quickly separate the mixture?

To separate oil from water, add a solution of soluble ionic salt to the solution. Distillation, which involves boiling and condensing the water, is another option, as well as partially freezing the oil and water combination and discarding one-fourth to one-third of the unfrozen water.
