Separate three Components from Iron, Sand and Common Salt Mixture

Materials Required:

A mixture of iron filings, sand and common salt, magnet (kept in a petri dish), Filter paper (On a paper box), Funnel, two beakers, Petri plate, glass rod, Burner, Tripod stand, wire gauze, a sheet of paper, Lighter, Spatula, Magnet piece, Water in a wash bottle



Real lab Procedure: 

  • Take a small amount of the given mixture of iron fillings, sand and common salt in a petri dish.
  • Spread the mixture on a sheet of paper.
  • Take a glass rod and using a glass rod spread the mixture.
  • Move a magnet over the surface of the mixture. 
  • Fill a beaker with the residual mixture after the iron filling has been removed.
  • Add a sufficient amount of water using a wash bottle to cover the mixture.
  • Stir the contents of the beaker with a glass rod for some time.
  • Place a tripod stand, keep the funnel in the tripod stand, fold the filter paper, and place it inside the funnel.
  • Filter the content with the help of a funnel and filter paper 
  • Place a tripod stand on the top of the burner and then place a wire gauze. Place the filtrate containing beaker on the tripod 
  • Turn on the burner and ignite the burner using a lighter.
  • Heat the filtrate obtained in step using a burner.
  • Heat the content till water evaporates.

Simulator Procedure:   

  • Drag the petri dish containing a mixture of iron filings, sand and common salt into the paper. 
  • Drop the petri dish into the paper to spread the mixture. 
  • Drag and drop the magnet over the surface of the mixture. 
  • Drag the paper containing a mixture of sand and common salt into the beaker. 
  • Drop the mixture into the beaker. 
  • Drag the wash bottle containing water into the beaker. 
  • Drop the water into the beaker. 
  • Click on the glass rod to stir the mixture.
  • Click on the ‘Next’ button. 
  • Drag and drop the funnel into the tripod stand. 
  • Drag and drop the filter paper into the funnel. 
  • Drag and drop the beaker containing sand and water into the funnel. 
  • Drag and drop the beaker containing water into the top of the wire gauze 
  • Click on the knob to turn on the burner. 
  • Click on the “HELP” button to get the required procedural steps.



  • Iron fillings stick to the magnet and are thus separated.
  • Sand remained undissolved in water and is separated by filtration.
  • On heating the filtrate, water is evaporated and a white coloured substance (common salt) is left at the bottom of the beaker.
  • Compare the separated components with the mixture you left aside.



  • Magnetic substances like iron are separated by a magnet.
  • Substances which are insoluble  in  water  (such  as  sand)  can  be  separated by filtration.
  • Substances which are soluble in water (such as common salt) can be separated by evaporation.



  • When working with an open flame, use extreme caution.
