10.8: Electronegativity and Polarity - Why Oil and Water Don’t Mix

Web2 de fev. de 2024 · The reason water and oil do not mix is due to the nature of their molecular structure. Water is a polar molecule, which means that it has a positive charge at one end and a negative charge at the other. Oil is nonpolar, meaning its charge is evenly balanced. Because of this, water molecules will only attract other water molecules, and … Web1 litre of cooking oil pollutes 1 million litres of water. As used cooking oil and other fats are dumped into waste bins, toilets and sinks, the contaminated sea significantly threatens underwater habitats and species.
