Q. 55
How will you separate common salt, sand and iron filings from their mixture?
Answer :
Use the magnet to remove the iron- Spread the sand, salt and iron mixture on a flat surface. Wrap the magnet in the paper towel. Use the magnet to remove the iron by pulling it across the surface of the mixture. The filings stick to the magnet while the sand and salt are left behind. Remove the paper towel from the magnet to collect the filings.
Use warm water to dissolve the salt- Put the remaining salt and sand mixture into the glass of warm water, and stir until all the salt has dissolved. The sand remains undissolved and hence can be collected from bottom of the jar. The salt solution can undergo process of evaporation for the separation of salt.
