how could you separate iron, sand and salt that has been mixed together with only using a filter, a magnet, and a Bunsen burner?
a magnet would pull the iron out of the sand and salt. Can you add water? If so you could add the sand and salt together with water. the salt would dissolve in water. You could use the filter to take the sand out of the saltwater/sand mix and then get the salt back by using the bunsen burner to heat up the leftover saltwater mix and evaporate the water
I think it was helpful from the questions as it gave me some answers
To separate iron, sand, and salt using only a filter, a magnet, and a Bunsen burner, you can follow the steps below:
1. Use a magnet to separate the iron: Place a magnet in a plastic bag and move it around near the mixture. The magnet will attract the iron particles, allowing you to separate them from the rest of the mixture.
2. Filter out the sand: Set up a filter funnel and a filter paper over a clean container. Pour the remaining mixture (containing sand and salt) into the filter funnel. The sand will be retained on the filter paper while the salt passes through as a solution.
3. Evaporate the water to isolate the salt: Pour the saltwater solution from the container into an evaporating dish. Place the evaporating dish on a Bunsen burner or a hot plate. Heat the dish gently, and as the water evaporates, salt crystals will be left behind.
Now, you have successfully separated the iron, sand, and salt using the given tools. The magnet was used to extract the iron, the filter paper separated the sand, and the Bunsen burner helped to obtain the salt by evaporating the water.
