Marc Oconnell · Answer 1

The best method to separates mixture of salt and water is evaporation. Take a small sample of mixture in a china dish. Heat it till all water evaporate. The residual remain is salt. Josh should use this method to separate salt from water.

evaporation

Explanation:

Evaporation is used in liquid and solid mixtures in which the liquid is evaporated. This method is effective when the liquid in the mixture easily evaporates, like water. Thus, we can conclude that evaporation would be the most efficient separation method for the student, shown in the question above, to use to separate the mixture of water and salt, because water would evaporate and salt would remain. This process is used in Brazilian salt flats to remove salt from seawater.
