Question

How will you separate common salt, sand and iron filings from their mixture ?

Answer 1

Answer:

Use a magnet to remove the iron filings. Add water to the salt and sand mixture to dissolve the salt. Pass the salt and sand mixture through a filter. Allow the liquid from the sand, salt mixture that you got through the filtration to evaporate leaving the salt. Marvel at the separated iron, salt and sand.

Answer 2

Answer:

hey

The filings stick to the magnet while the chalk and salt are left behind. Remove the paper towel from the magnet to collect the filings. The mixture of iodine and salt is separated by the process of sublimation. When the mixture of iodine and salt is heated, then iodine sublimates and salt is left.
