What are physical and chemical properties that could be used to distinguish water and a saltwater solution?

Answer 1

The two techniques for separating an insoluble solid from a liquid are filtration and centrifuging. Filtration relies on the fact that the solid particles are smaller than the filter paper pores which allow the tiny molecules of liquid to pass through. With solids which dissolve in a liquid solvent, evaporation is commonly used to recover the solid and distillation is used to recover the solvent.

Answer 2

Salt water boils at a slightly lower temperature than distilled water. Also you wont be able to dissolve any other compound containing the Na atom into salt water if the solution is already saturated.

Answer 3

salt is when mixed to the water, the particles of salt are dissolve in the water and to separate it we use evaporating dish. when we boil the water in the beaker the water is evaporated and the salt remains in the beaker.

Answer 4

Physical properties such as boiling point and freezing point can distinguish water (pure) from a saltwater solution, as the presence of salt will change these values. Chemical properties like conductivity can also differentiate the two, as saltwater will conduct electricity due to the presence of ions, whereas pure water does not conduct electricity.

Answer 5

Taste. density.

Answer 6

Solubility.
