Explanation:
please follow me
Answer:
• Water Soluble
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. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.
•Pour the mixture in a container having water and stir well. The salt will dissolve in it.
2) Now pass the mixture (aqueous) into another container using a sieve. The sand and the solution will pass through sieve and the pebbles will get separated out.
• which rice grain with sand will be filtered out and remaining water, salt will be filterate after that we can use handpicking for saperating sand and rice grain on the other hand evaporation to saperate out salt and water.
• A mixture of 'sawdust and water' cannot be separated by 'sedimentation and decantation'. EXPLANATION: Sedimentation and decantation is the process of separation of solid that is heavier than liquid by pouring out the liquid after the solid is 'settled at the bottom' of the vessel.
