question 6

1. what physical property can be used to separate a mixture of salt and water?

filtration
evaporation
hand separation
chromatography

Explanation:

To separate salt (a solid solute) from water (a liquid solvent) in a mixture, we use the physical property related to the different boiling/evaporation points. Filtration is for separating solids from liquids when the solid is insoluble, hand separation is for visible large - particle mixtures, and chromatography is for separating components in a mixture based on their different affinities in a mobile and stationary phase. Evaporation works because water can evaporate (turn into vapor) at a relatively low temperature, leaving the salt behind.

Answer:

B. Evaporation
