Emulsification Lab Report

Research Question:
What effect do the different chemicals have on the rate of emulsification?


The combination of two different liquids that are not able to mix well together is called emulsification. When you use emulsification with fats, water-based substances are useful here, and this is how people have the ability to cook and also digest. Bile salts and other compounds that accompany it are used when you have to emulsify fats. This is because it helps both the fat and the water find a way to connect.

The different variables


The chemicals that are being tested


The time that the oil takes to separate
The time that the water takes to separate


Amount of oil being used
Amount of water being used
Amount of chemicals added
Time shaking test tube



2ml of oil
2ml of water
1ml of various chemicals to test
Test tubes


Before starting this, you want to take out two empty beakers and label both of them. Label the first beaker with oil or fat and the second beaker with water. Fill up the beaker depending on the number of people you have that are doing this experiment. After you have labeled you want to grab a pipette and with that pipette you want to grab 2ml squared of water and try not to go higher or lower. Put that 2ml-squared water into one of the test tubes that you have labeled and after doing that you want to repeat that procedure for the second test tube as well. After you have 2ml squared of water in each of your test tubes you want to add 1ml squared of the chemical that you are using. Continuing the experiment, you then want to put your thumb over the test tube and then shake the test tube five times. Next, get a stopwatch and with that you will see the time that it takes to separate the chemicals. When you are done with this you want to stop the stopwatch...
