What physical property would be the most useful in the separation of very fine saw dust and salt?

the particle size of the components
the density of the components
the solubility properties of the components
the magnetic properties of the components

Respuesta :

The solubility properties of the components.

Salt is soluble in water so the mixture may be placed in water and then filtered. The saw dust will be retained on the filter paper.
