Dip Lab

Today during science we experimented with water, alcohol and different pens. It more interesting than it sounds.We got pieces of paper and drew a dot or a different pattern on it with different types of markers then put it into a cup with little water on the bottom. As the paper soaked the water went up the paper because the water was polar and since the marker was also polar the water pulled the marker up with it.

The first photo shows the original pattern. There are only four different chemicals on this paper. The second paper is when we soaked it in water, and the second we soaked it in alcohol. The color from the marker spread out or overlapped. This method helps you find out, which of the markers chemicals are most polar and which least. The pictures were taken upside down so the dark blue in the corner was dunked in first. The chemical which went in first, dark blue, is the least polar, however the third chemical, Green, is the third least polar. The color which spread the most is the color which is the most polar since water is polar as well so it would mix with the water the best.

The difference from the water and alcohol is that in the water it spread much more. This is because the markers are polar, and alcohol is less polar, so they wouldn't mix as well as water and the ink. 












Here is a photo of all the tests we did. The first image is for water and the second for alcohol.
