Iron Filings
Problem: What methods could be used to extract materials from the given mixture that contains iron filings,sand,salt and small stones?
Background There are things that must be understood before doing this lab. The first thing that must be understood is a mixture. A mixture has two or more pure substances, and the substances keep their chemical compositions (study.com).The next thing to apprehend is filteration. Filtration is a method used to separate a solid that isn’t dissolved in water. Another method is magnetic separation. Magnetic separation is used when there is a magnetically charged material in a mixture and is extracted by a magnetic force. The last method that could be used is evaporation. Evaporation separation is used by heating …show more content…
Materials The materials that are need are iron filings, salt, small stones,sand, beakers, water, magnet, bunsen burner, striker, ring stand, wire gauze, ceramic square, a funnel and water.
Procedure
The first step is to take out the stones out of the mixture from the beaker.
The second step is to use a magnet to get the iron fillings out. The iron filings are attracted to the magnet, so they will attach to the magnet. Before using the magnet put a paper towel around the magnet, or the iron filings will be nearly possible to get it all off.
The third step is to add water to the sand and salt, so it can be ready to filtered.
The fourth step is to fold a paper coffee strainer. Make sure the fold is the correct size to fit in the funnel and add a little bit of water to the sides of the coffee strainer, so it remains opened. The reason for doing this because the salt will go through the coffee strainer while the sand does not.
The fifth step is to pour the beaker with the salt and sand into the funnel and let it filter the sand and salt. Also, make sure to have a beaker underneath the funnel to catch the salt …show more content…
Let the salt water boil, so the water can evaporate. Keep waiting until there’s a salt ring in the beaker.
Results. The results for this experiment is the materials were all separated. There was no method to take out the stones except to use your hand to get the stones out. Magnetic separation was used to separate the iron filings which it did. The next method was filteration that was used once water was added to separate the sand and salt water. The last method which was evaporation which the water evaporated when the water was heated and left the salt ring in the beaker.
Conclusion The results proved that the methods used worked. An example is, once the water was added to the sand and water, then it was filtered through a coffee strainer. Since salt dissolves in water and sand is a solid that does not dissolve, the sand is either left in the beaker or left in the coffee strainer while the salt water is filtered through. Other classmates who were doing the same experiment and same procedure had quite similar
