BIOL&242/ROBINSON Part 1: Lipids MATERIALS: 2 jars 1 is water w/food coloring, the other is vegetable oil NAME CHEMICAL DIGESTION-LAB NOTES A few drops of the colored water were added to the oil in a glass jar What do you observe? Can you get the oil and water to mix? What can you try? Screw the lid onto the jar. Give one hard shake. What do you observe? What happens if you let the jar rest? Does all of the water eventually get to the bottom? So, if the tiny drops stay suspended, what if we make the water into very tiny droplets. Shake the jar vigorously for several minutes. What do you observe? Does the water take longer to settle out? This is called a suspension of water in oil.Explanation / Answer
please find the answer
experiment 1 lipid
In the first experiment there is two seperate layer of oil and water
they are not mix to each other.
The first thing you will observe is that Oil and Water won’t stay mixed together. Instead, the oil slowly rises to the top of the water. This is because of the density of the two liquids. The oil is less dense than the water, therefore it rises to the top.
experiment 2 emuslion
The second thing you will observe is that including Dish Soap in the mixture, changed the result of the experiment. When Oil, Water and Dish Soap are mixed together, the Oil and Water don’t separate like they did when they were the only two items in the jar. This is because the dish soap is attracted to both the oil and the water and helps them both mix and stay mixed together.
this is because of emuslion property o/w mixing.
