Mar 31, 2019 · A combination of fluids results in a mixture that is different from the two parts added. This is an explanation of the miscibility of fluids.
- Anne Marie Helmenstine, Ph.D.
What about two different compounds? It turns out that whether two different compounds interact with each other depends on the same kinds of interactions we have looked at so far. Two liquids that do not really mix well together, such as oil and water, are described as immiscible.
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.
A mixture is a combination of two or more substances in any proportion. This is different from a compound, which consists of substances in fixed proportions. The substances in a mixture also do not combine chemically to form a new substance, as they do in a compound.
Sep 12, 2022 · If two atoms have identical, or similar EN values, their nuclei both pull on the shared electrons nearly equally. This equal sharing is called a nonpolar covalent bond – neither nucleus has a greater electron density after forming the bond than it did before forming the bond. Examples: H-H, F-F
May 1, 2024 · Key Takeaways: Mixture. A mixture is formed by combining two or more materials. A homogeneous mixture appears uniform, regardless of where you sample it. A heterogeneous mixture contains particles of different shapes or sizes, and the composition of one sample may differ from that of another sample.

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. Those with similar chemical properties will mix; those with different properties will not mix.
