Question

Iron fillings in sawdust can be separated by means of

Answer 1

Iron filings can be separated by magnetic separation method. When water is added to the mixture, sugar becomes soluble in water leaving behind sw dust, when this is filtered, saw dust can be separated as a residue. The filrate saw dust can be separated as a residue.

Answer 2

Iron fillings in sawdust can be separated by the means of magnets.

• Magnetic separation is the method of removing magnetic material from a mixture using a magnetic force.
• Sawdust is a non-magnetic material whereas Iron filings are magnetic.
• The iron filings will be attracted to magnets, but sawdust will not, resulting in the separation of the iron filings and sawdust.
• Magnets are placed inside two separator drums that contain liquids in this operation. Magnetic materials are drifted by the movement of drums due to the presence of magnets. This can result in the formation of a magnetic concentration.
• This method can be applied to ferromagnetic and paramagnetic materials.
• Iron is a metal with the atomic number 26 and the symbol F.
• It belongs to the periodic table's first transition series and group 8.
• The potential of transition metals to create magnets is an intriguing property.
• Unpaired electrons in metal complexes make them magnetic. This magnetism must be owing to the presence of unpaired d electrons because the last electrons are in the d orbitals.
