Abstract
Polar solvents dissolve, or pick-up, polar substances and non-polar solvents dissolve, or pick-up, non-polar substances. In the conducted experiment, the polarity of molecules and their properties are explored. The results of using two solvents on both polar and non-polar inks, further verify this to be true. The student conducted the experiment given, using safe lab practices, that found the polarity of two seperate solvents, and it has been shown through experimental results that the hypothesis formed in the beginning of this experiment is true. It has been deducted from this experiment …show more content…
Manipulate the slime in your hands. Write down observations made about how slime pours, stretches, breaks, etc. in Part 1 of the Data section.
CAUTION: Slime is slippery and if dropped it can make the work area slick.
8. Place the slime back into the beaker and WASH YOUR HANDS.
Part 2: Slime and Putty Ink Tests
1. On a piece of notebook paper make one 20 - 25 mm long mark of each of the inks you are testing (permanent marker, highlighter, Dry Erase, and Uni-ball® Roller Pen). Space the marks at least one inch apart. Use a pencil to label each mark with its description.
a. Water soluble inks include those in highlighters and certain pens.
b. Water insoluble inks include those in a permanent pen/markers, newsprint, and a dry-erase markers.
2. While the inks are drying, select a passage or a picture in the newspaper to test with the slime.
3. Develop a hypothesis stating whether or not you believe the slime produced in Part 1 will pick up newsprint ink. Record this hypothesis in the Post-Lab Questions section. Then, break off a small piece of slime that is 3 - 5 cm in diameter. Gently place this piece on top of the newspaper print, then carefully pick it up again.
4. Observe and record in Table 1 whether or not the ink was picked up onto the
