Question

How would you seprate a mixture of sand and iron fillings​

Answer 1

I WILL SIMPLE USE A MAGNET.

THE IRON FILLING WILL STICK TO THE MAGNET AND THE SAND BEING NON-MAGNETIC WILL BE SEPERATED.

TO BE FRANK THIS METHOD IS ALSO INCORRECT AS SAND CONTAINS SOME AMOUNT OF IRON SO SOMETIMES IT ALSO TICKS TO THE MAGNET.

BUT THE GENERAL ANSWER IS USE MAGNET.

PLEASE MARK AS BRAINLY answer

Answer 2

Answer:

Iron is magnetic and the other two not, which means a magnet could be used to attract the iron filings out of the mixture, leaving the salt and sand. Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.
