Abstract: In this lab experiment, my group and I purified foul water. This was a long and tedious process but we got it done. Although, we did have trouble when we got to step 17. We accidentally skipped the step of pouring the foul water with the charcoal into the filter paper, instead we put the charcoal straight into the filter paper and poured the foul water on top and we got water with the charcoal particles inside so it turned black. Eventually we went back, and mixed everything together, and got a new filter paper, and by the end, we had clean water.

Procedure:

1.Prepare a data table to provide information about the lab experiment

2.  Use a clean beaker with about 100 mL (milliliters) of foul water, and measure the volume with a graduated cylinder.

3.  Place notes in the data table of the appearance, color, clarity, and smell of the original sample.

4.   Let the sample sit in the graduated cylinder for a few minutes.

5.   Take a clean Beral pipet, and remove as much upper liquid from the foul water into a clean test tube.

6.  Add distilled water to the liquid placed in the test tube. Observe if the water floats to the top or sinks to the bottom.

7.    Take the volume of the liquid sample remaining in the gradated cylinder.

8.    Throw away the in the test tube.
9.    Poke holes into the bottom of a Styrofoam cup.
10.  Add 1cm of gravel as the bottom layer, 2 cm of sand as the middle layer, and to top it off, another 1 cm of gravel.

11.Pour the sample into the cup so it will filter it. Catch the filtered liquid in a beaker.

12.Throw away the used sand and gravel.

13.  Look at the characteristics of the filtered water sample and the measurement of its volume. Save the water sample for the next procedure.

14. Fold a piece of filter paper.

15. Place the folded piece of filter paper in a funnel, and wet it so that it will stick against the base and the sides of the cone.

16. Place one level teaspoon of charcoal in a 125-mL Erlenmeyer flask.

17. Pour the water sample into the flask, and swirl it around for multiple seconds. The pour the liquid into the filter paper in the filter cone.

18. If darkened by small charticoal particles when filtered, redo step 17.

19.  When satisfied by the color and the smell, place it back into a graduated cylinder and record the final volume and properties of your purified sample.

Conductivity: The purified foul water is a conductor for electricy and contains positive and negative charges due to the salt and other particles that werent completely filtered out.
