First, we began the lab by putting on all of our safety gear. Goggles, apron, and started the fume hood and put the Hexane under the fume hood.

Statement of the Problem:

* Which Mixtures separate water soluble overhead pens. (Red, Black, Green, Yellow, and Blue)

* We knew that water would be the most soluble, and that Hexane we were using was toxic so we had to put it under the fume hood.

Hypothesis:

* The way that we will be able to test this is to test the many different mixtures to see which one is most soluble.

Materials:

*Goggles, apron, 24 well rack, water other mixtures, paper strips, and markers.

*Started the fume hood and put the Hexane under the fume hood, goggles, and apron.

Procedure:

* 1. First, we began the lab by putting on all of our safety gear. Goggles, apron, and started the fume hood and put the Hexane under the fume hood.

2. Then we gathered all the needed items; the 24 hole well plate, the thin slices of paper, and markers. After that we began the lab, the first day we used different solutions with the same color pigment.

3. We used H2O, C3H7OH, CH3OH, and C4H14. The H2O spread the color pigments out the most. C3H7OH spread it out not as much but thicker. CH3OH did not spread the pigments out very much compare the H2O and C3H7OH. C4H14 did not spread the color pigments out at all.

4. Waited 30 minutes for the color to spread after sitting in the mixture. Then recorded the results and made a graph of how the color was distributed for each one.
