- Some liquids, like orange juice and water, mix together easily and become a special kind of mixture called a homogeneous mixture. In this type of mixture, you cannot tell the liquids apart anymore—they blend completely (Figure 1, left). We call these liquids miscible. Other liquids, like oil and water, do not want to mix; they stay separate.

A simple rule, "like dissolves like," can tell you which liquids mix and which do not. Liquids with similar polarities are miscible, whereas liquids with different polarities do not mix. Water is a polar liquid, but oils are nonpolar. This is why oil and water do not mix well.

- Excess Volume: Investigate the "Shrinking Liquids" Effect
When two liquids combine to form a new liquid, we call the liquids “miscible.” When two liquids do not mix together and instead form layers, we call them “immiscible.” The chemical properties of the liquids will determine if they will mix or not.
In this science project, you will investigate how the mixing ratio of two different liquids affects the excess volume of the mixture. We will use the mole fraction as a way to measure how much of one type of molecule there is in the mixture.

“Oil and Water” is perhaps the most common example of two immiscible liquids. No matter how much you mix oil and water, they do not mix. The reason this happens is because of the chemical nature of oil and water molecules. There is a popular saying in chemistry that “like dissolves like.” This means that polar liquids (like water) dissolve in other...
Kerosene, also known as paraffin, is a combustible hydrocarbon liquid that is derived from petroleum. It is widely used as a fuel in aviation as well as in households. It is a low viscosity clear liquid that is made of 10 to 16 carbons chained hydrocarbons obtained from the fractional distillation of petroleum at 150 to 250 °C. Like many other hydr...
During the rainy season, one of the major concerns of the people who own a vehicle is that if water sweeps into the fuel tank, it may cause harm to the engine. Modern cars have good sealing against water. However, there would be a chance in which water does come into your car’s fuel tank. So what if water gets in the fuel tank? Gasoline or petrol i...
Another most common example that one can find in their kitchen for two immiscible liquids is corn syrup and vegetable oil. Corn syrup is a sweet syrup produced by milling corn into cornstarch and then putting the cornstarch through the process of acid hydrolysis. The density of corn syrup is approximately 1.4 g/mL. Corn syrup is almost entirely mad...
If you visit a home decor store, you may come across an interesting kind of lamp known as the Lava lamp. They are also an interesting example of immiscible liquids. The lamp consists of a bolus of a special colored wax mixture inside a glass vessel, the remainder of which contains clear or translucent liquid. The working of a lava lamp depends prim...
Jan 30, 2023 · Truro School in Cornwall. This page deals with Raoult's Law and how it applies to mixtures of two volatile liquids. It covers cases where the two liquids are entirely miscible in all proportions to give a single liquid - NOT those where one liquid floats on top of the other (immiscible liquids).
Oil and water are two liquids that are immiscible – they will not mix together. Liquids tend to be immiscible when the force of attraction between the molecules of the same liquid is greater than the force of attraction between the two different liquids. In simpler terms - like dissolves like!

Jan 10, 2023 · The difference in composition between the gas and the liquid can be exploited to separate the two components, at least partially. We could trap the vapor and cool it down to form a liquid with a different composition. We could then boil it again and repeat the process.
