Question

if you were wanting to separate sand from a mixture of salt water and sand, what separation technique would you use? filtration distillation

Explanation:

Filtration is used to separate insoluble solids (like sand) from liquids (like salt water). Sand is insoluble in water, so passing the mixture through a filter (e.g., filter paper) will trap the sand while allowing the salt water to pass through. Distillation is used to separate components based on boiling points, which is not suitable here as we want to separate the solid sand from the liquid mixture.

Answer:

filtration
