An emulsifier is the best mixing element that allows oil and water to mix together. One of the good references examples of this is detergent.
Mixing Oil and Water
Do you know something? Whatever magic you do, few elements never become friends with each other. The best example is oil and water, you just try to mix that both together, they never go with each other. Or do they mix? You can try out this experiment on your own, just check out what happens when you mix oil and water together can help you do your dishes.
For this, you will need Water, Food coloring, Small soft drink bottle, Dishwashing liquid or detergent and 2 tablespoons of cooking oil
Make sure to follow the below Instructions:
- Add one o two drops of food coloring into the water
- In a small soft drink bottle, add about two tablespoons of the colored water and two tablespoons of cooking oil
- Just shake the bottle as much as you can after closing the lid
- Check out what happens after keeping the bottle down. You can find the elements are mixing together but actually the oil will be floating on the top.
Do you want to know the reason behind what has happened?
Generally, water mixes with any liquids to form solutions, but oil never mixes with water. The strong reason behind this is, both water and oil molecules get attracted strongly to each other since they get attracted to their own molecules, and hence they don’t mix together. Because of the oil with lower density, they get separated from water and floats above the water.
In an exceptional case, if you want both to get together, try to add some dishwashing liquid or detergent. These Detergents get attracted to both water and oil, which helps to join all together and form a substance called an emulsion. This emulsion is used in washing greasy dishes that take off the oil and cleans the plates.
