MM 3.5: Models of Emulsifiers

We know that oil and vinegar will mix together and not separate into layers when an emulsifier is added to them. Let’s take a closer look at the way these liquids mix. These images show, step by step, what happens when oil, vinegar, and lecithin mix. The last image is a zoomed-in image of the completely mixed liquids.

What evidence do you see that shows the liquids are mixing - from the first to the last photo?

In the photo, it shows ____________________

How do you think the lecithin gets oil molecules and vinegar molecules to mix?

The lecithin gets oil and vinegar molecules to mix because _____________________

Drawing Nanovision Models of Emulsifiers

Follow the instructions on the worksheet. Make your model to show what happenes when an emulsifier (lecithin) is added to oil and vinegar on paper.

Steps to get to the Emulsifier Simulation
1) Click on the 3 lines in the upper left corner
2) Choose Emulsifier

Trial 1: Add molecule 5 and molecule 6 in the dish. Are they attracted to one another and mix?

Trial 2: Add molecule 5 and molecule 6 in the dish. Now add the emulsifier molecule. Mix them with the help of an emulsifier. Are they attracted to the emulsifier and mix?

How did the emulsifier’s shape help to mix the molecules?
