Question

2. Which method you will use to separate:

(a) Iron from sand and salt.

Answer 1

• A mixture of sand, salt, and Iron is separated by using a magnet.
• A magnet is used to extract the iron filings.
• After that, sand and common salt are mixed in water.
• While salt dissolves in water, sand does not. So, sand is separated by filtration or decantation.
