Question

Describe the best method for separating a mixture of sand, salt, and steel shavings by placing the steps below in the correct order

Answer 1

4 Heat the mixture to evaporate the water.

3

Pour the mixture through a filter to separate the sand.

1

Pass a magnet over the mixture to remove the steel.

2

Add water to the sand/salt mixture and stir to dissolve the salt.

Answer 2

Perhaps sift the mixture, or expose it to a magnet, to separate the steel shavings from the rest of the mixture. Then, boil the remaining sand and salt in water, so the salt will disintegrate and only the sand will be left. Then, you could drain the water into a sifter, so the sand will be caught and seperated from the salt water.
