Hello, I'm a specialist in the field of fluid dynamics and chemistry. It's quite fascinating to discuss why oil floats on vinegar, and I'm here to provide you with a comprehensive explanation.
Firstly, let's understand the basic principles of fluid dynamics and the properties of the substances involved. Oil and vinegar are two different types of liquids with distinct physical and chemical characteristics. The phenomenon of oil floating on vinegar can be primarily attributed to the differences in their densities and the interactions between their molecules.
Density is a key factor in determining whether one substance will float on another. Density is defined as mass per unit volume, and it varies from one substance to another. Water, which is a major component of vinegar, has a density of approximately one gram per cubic centimeter at room temperature. The density of oil, on the other hand, is generally less than that of water, which is why oil floats on water. This principle also applies to vinegar since it is predominantly water with some dissolved acetic acid molecules.
The molecular structure of oil and vinegar also plays a significant role. Oil is composed of long-chain hydrocarbons, which are non-polar molecules. This means that they do not have a separation of charge and do not form hydrogen bonds with water, which is a polar molecule. Acetic acid, the main component of vinegar, is a polar molecule due to the presence of a carboxyl group (-COOH). However, the overall polarity of vinegar is still less than that of water, and the oil's non-polar nature means it does not readily mix or dissolve in vinegar.
When we talk about impurities, they can affect the density of oil. If oil contains impurities that increase its density, it may become denser than vinegar and thus not float. However, under normal circumstances, the density of pure oil remains lower than that of vinegar, allowing it to float.
Another aspect to consider is intermolecular forces. The strength of these forces determines the solubility and miscibility of substances. Oil, being non-polar, does not have strong intermolecular forces with the polar molecules of vinegar. This lack of interaction means that oil does not dissolve in vinegar and instead forms a separate layer on top.
Lastly, the temperature and pressure can have minor effects on the density of liquids, and thus on their ability to float one on another. However, these effects are generally negligible in everyday situations and do not significantly alter the basic principle that oil floats on vinegar due to its lower density.
In summary, oil floats on vinegar primarily because of its lower density compared to vinegar. The non-polar nature of oil and the weaker intermolecular forces between oil and vinegar molecules also contribute to the separation and the floating phenomenon. Impurities in oil can potentially increase its density, but under typical conditions, oil remains less dense and floats on vinegar.

They don't mix in water and will float. Adding impurities to the oil may make it more dense however. ... Water has a density of about one gram per cubic centimeter (depending a little on temperature and pressure). Household vinegar consists almost entirely of water, but with some acetic acid molecules dissolved in it.
