Sand and Salt Lab
Period: 2, Viktor Voytanovych (lab partner: Nick Udell)

Purpose: The purpose of this lab was to separate salt from sand using water and methods of filtration and evaporation.
Materials:
 Sand and Salt Mixture (dry)
 Spray Bottle
 Filter Paper (dry)
 Water
 Funnel
 Beaker
 Bunsen Burner
 Erlenmeyer Glass
 Graduated Cylinder
 Support Ring
 Wire Gauze
 Scoopula
 Striker
 Hot Hand
 Piece of Paper
 Scale
 Rod
 Goggles
Procedure:
1. In the beginning, you would take 3.75 grams of the pre-made sand and salt mixture (make sure to measure and record the data).
2. After that, place the sand and salt mixture into a clean beaker.
3. Then, measure the weight of the Erlenmeyer flask in grams with the scale (record the data).
4. After that, measure the weight of the filter paper in grams with the scale (record the data).
5. Then, take the clean graduated cylinder and fill it with about 10 mL of water.
6. After that, pour the water into the beaker with the measured sand and salt mixture.
7. Then, fold the filter paper into a cone shape and place it into the funnel and spray some water on the filter paper to make it stay in that cone position.
8. After that, place the funnel into the clean Erlenmeyer flask.
9. Then pour the water with the sand and salt mixture into the funnel with the filter paper ( use the spray bottle to get some of the mixture off if necessary).
10. After that, remove the filter paper with sand and place it somewhere where it won’t spill but will dry.
11. Then, attach the support ring and wire guaze to the rod of the Bunsen burner.
12. After that, turn on the gas to the Bunsen burner (make sure you meet all the safety requirements beforehand).
13. Then, light the Bunsen burner with the striker (make sure you know how to use one beforehand). 14. After that, place the Erlenmeyer flask on top of the wire guaze with a hot hand while the
Bunsen burner is lit.

15. Then, wait until the water evaporates then take off the Erlenmeyer flask with a hot hand and place it on a piece of paper to cool off.
16. After that, turn off the gas to the Bunsen burner while being careful not to get burned.
17. Then, wait until both the paper and glass dry/cool off.
18. After that, measure both the paper and flask with their contents inside with a scale separately.
19. Finally, figure out how much sand and salt was saved with simple subtraction.

Separation Anxiety Experiment Summary

was to thoroughly divide a salt and sand mixture by applying our knowledge of separation techniques, in order to determine the mass and percent composition of the isolated salt and sand in comparison to the original heterogeneous mixture. To accomplish this experiment, 25 ml of water was first added to the beaker containing the mixture. The water in combination with the salt and sand mixture was stirred, allowing the salt to dissolve into the water. Then, the sand and salt solution were segregated…

successfully separate a mixture of iron filings, poppy seeds, sand, and salt using the lab equipment provided. Hypothesis: In order to separate the iron filings we need to use a magnet. To separate the sand and poppy seeds we need to mix the remaining mixture with water and filter it, the poppy seeds will float and we will be able to remove them with a spoon. We can then scoop the wet sand into a separate cup and boil the salt out of the salt water. Procedure: First we dragged the magnet through…

of a liquid or solid changing into a gas To separate the mixture of salt and sand first you must put the mixture in water and stir it up. Since the salt is soluble and sand is insoluble, the salt will dissolve in the water and the sand will stay. Then you can use a filtration to separate the salt water from the sand. The filtration should keep the sand in and the salt water will go through it. Separating a salt, sand, iron fillings, and sesame seed mixture: 1. Use a magnet over the mixture…
