Question

Give scientific reason for the following :
Mixture of sand and iron fillings is heterogeneous mixture.

Answer 1

Hey Friend!

Here's your answer!

Heterogenous mixture doesn't mean if the mixture is uniform or is dissolved, but the actual basis on which 'heterogenous' is classified is that ☛ The components of a Heterogenous mixture can be separated through physical methods like handpicking, magnets, centrifugation etc.

For the mixture of sand and iron filling, they can be separated by physical means by using a magnet.

And therefore, mixture of sand and iron fillings is classified as Heterogenous mixture.

Answer 2

Because they are not mixed evenly or uniformly and they can be easily separated from each other by physical methods and they can be seen through naked eyes.
