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.
Sand and Salt Mixture (dry)
Filter Paper (dry)
Piece of Paper
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.

Filter Paper with Contents
An extra measurement was the 10 mL of water poured into the graduated cylinder. A couple of errors could have been measuring the mass of the objects incorrectly, adding to much water in the process of evaporating the water, and
