Answer 2

Rita by mistake dropped some iron filings into a mixture of sand and water. Method to separate the mixture is by using magnet and then filtration.

Explanation:

• When sand and iron fillings are added to water then it will lead to the formation of a heterogeneous solution as both of these substances are insoluble in water.

• So, when we add a magnet into this solution then it will attract all the iron fillings due to the force of attraction exerted by the magnet on the iron fillings.

• Whereas only sand will be left behind into the water which can be separated by by filtration. Therefore, the solute from the solvent (water) are separated out.
