Why do Oil & Water not mix? I'm so confused (This is just something I wanna know, no multiple choice) also,
Ms. Sue, If you see this, Hi
Also, Ms. Sue, Are u famous on Jiskha?

LOL! I don't know about being "famous."
Literally, I see u on EVERY SINGLE THREAD! xD and thank you so much, Ms. Sue! <3
You're welcome, Melanie.
Hi there! I can explain why oil and water do not mix.
Oil and water do not mix because they are immiscible, which means they cannot form a homogeneous mixture. This is due to their different chemical properties.
Oil is a hydrophobic substance, meaning it repels water. It is composed of nonpolar molecules that do not have a charge and are repelled by the polar molecules in water. Conversely, water is a polar substance made up of polar molecules.
The polarity of water arises from its bent molecular structure and unequal distribution of electrons, resulting in a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. Oil molecules, on the other hand, are nonpolar and lack these opposite charges.
Because of these differences, when oil and water are combined, the oil forms droplets or a separate layer on top of the water. This separation occurs because the intermolecular forces between like molecules (water-water and oil-oil) are stronger than the intermolecular forces between unlike molecules (water-oil).
To observe this phenomenon, you can conduct a simple experiment at home. Take a glass of water and add a few drops of vegetable oil. You will see that the oil forms distinct droplets that do not mix with the water but instead float on the surface.
I hope this helps you understand why oil and water do not mix! Let me know if you have any more questions or if there's anything else I can assist you with.
