The salt will dissolve and the sand will not. What method is used to separate salt from a mixture of iron and salt? Explanation: Of course you could do the separation chemically. Dissolve the salt up in water, pass thru a filter, wash the iron filings with ethanol, which would encourage the salt to precipitate from solution.

Separating salt, iron fillings and sand Background: Iron is a metal, and therefore it sticks to a magnet, so magnetism can be used to remove the iron fillings from the mixture. Salt is a solute, and can be dissolved in water. Sand is not soluble in water, and so sand can be filtered from the solution. Salt water solution can be separated through evaporation, …

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. The salt will dissolve and the sand will not. These differences form the basis for separation of the three materials.

Solution. We can use a magnet to separate the iron filings from the mixture of common salt, sand and iron filings. Sand and salt can be separated by adding them to water and allowing the salt to dissolve and the sand to settle. When the water is decanted (filtered), sand is left behind. By boiling the decanted water and letting it evaporate ...
