DISCUSSION 1. Using what you learned about the structures of soap and micelles, explain what would map if soap molecules were mixed into a sample of pure vegetable oil. You may provide an illustration to help support your explanation. 2. Using what you've learned previously about light's interaction with matter, and what you've observed with the Tyndall effect, explain why the sky appears blue. (Hint: read the introduction to this experiment.)

What intermolecular forces are present when glycerin, water, canola oil, and dish soap are mixed? Lab procedure: 1. Glycerin and water are added to a test tube. There are now two layers: glycerin on bottom and water on top. 2. Canola oil is added to the tube and stirred; there is now a water/glycerin layer on bottom, and canola oil layer on top. 3. Dish soap is added to the tube and stirred; all parts are now mixed, then separate...

For a chemistry lab about a saponification reaction, why would you test your soap using CLR in the hard water reactions, shaking until you see a change? This is from the hard-water reaction section of the lab. Each test tube had dissolved natural soap in water. CLR was added to tube #1 with 5% CaCl2 added prior, tube #2 with 5% MgCl2 added prior, and into tube #3 with tap water added prior. Tube #1 turned white and layered Tube...
