'How might you separate a mixture of sand iron filings salt and sugar?

Answer 1

First rub a magnet through the mixture for a while this will remove all the iron.

Pour the salt/sugar and sand into water, and stir it. What settles at the bottom will be just sand.

Use a filter paper and pour the solution and salt onto it to get the salt onto the filter paper while the salt, sugar that is dissolved in the water will pass through.

boil the solution to find only sugar and salt at the end

Heat the mixture. The sugar will melt and the salt, being denser than the molten sugar and having a much higher melting point, will sink to the bottom and the sugar can be poured off or drained through an appropriately fine mesh screen.

Answer 2

Starting with the mixture follow these steps:-

1. use a magnet to remove the iron filings
2. Pour an alcohol over the remaining mixture and stir well (this will dissolve the sugar). Drain of the liquid and evaporate the alcohol to leave the sugar.
3. to the remaining mixture add water (this will dissolve the salt). Drain off the liquid and evaporate the water to leave the salt.
4. The remaining solid is sand.
