Explanation:
The best way to separate the mixture is by using a bar magnet. We explore the magnetic property of the iron fillings in the mixture to separate it out.
- The mixture is spread out thinly on a flat surface.
- A bar magnet is hovered above the spread of the mixture
- The magnet attracts the iron fillings to itself
- This will leave the salt behind in the mixture.
