Question

Iron filings were mixed together with salt crystals. What unique property of iron would be BEST to separate the filings from the salt?

Answer 1

Answer : Iron has a magnetic property.

Explanation :

Iron and salt crystal can be separated by the physical means. As we know that the iron has a magnetic property and salt crystal has no magnetic property. Iron is attracted towards the magnet. So, by using magnet we can separate out the iron filling from the crystal salt

Hence, the magnetic property of iron will help us to separate the filings from the salt.

Answer 2

Iron has magnetic properties, so you would just need to hold a magnet over the mixture and the filings will come right out.
