Oil and water have long been known to be incompatible. Oil and water are two persons that are constantly at odds with one another. When blended in a single container, the oil layer does not dissolve in water and tends to float to the top. However, under some conditions, oil and water can interact. This simple experiment explains the event of oil and water uniting.
Tools and Materials of Simple Experiment – The Uniting of Oil and Water
Bottles or small containers with lids
Cooking oil (leftover cooking oil can be used)
A few drops of dish soap
Instructions for Use of Simple Experiment – The Uniting of Oil and Water
1.Pour enough water into a container/bottle with a lid
2. Pour the oil into a container of water
3. Wait and see what occurs. The oil layer is on top of the water.
4.Cover the container, shake for a while. The oil solution will break but soon reunite but still can’t mix with water
5. Add two drops of dish soap to the oil and water mixture
6.Cover the container, then shake for a while
7. See what happened. Oil and water combine to form a cloudy solution.
Explanation of Simple Experiment – The Uniting of Oil and Water
Because of their differing molecular characteristics, oil and water do not combine. Water molecules are called polar molecules. Polar molecules have a positive charge on one side and a negative charge on the other. Polar molecules form strong intermolecular hydrogen bonds with one another.
The molecule in oil is non-polar. Oil molecules can only form bonds with non-polar molecules. Because the sorts of molecules in water and oil are different, they cannot combine and bond to each other. However, when you add dish soap and shake the container, the oil can mix with the water. This is due to the fact that soap is a chemical with a molecule with a polar base and a non-polar base. This soap’s polar and non-polar molecules work as a binder between oil and water. The soap is referred to as an emulsifying component in this scenario. To combine two difficult-to-combine liquids, an emulsion is required. The oil-binding nature of soap is very useful when used to wash dishes and cooking utensils that are full of traces of oil.
