Miscibility

Name:
Miscibility
Detailed information:
The ability of a liquid or gas to dissolve uniformly in another liquid or gas. Gases mix with one another in all proportions. This may or may not be true of liquids, whose miscibility properties depend on their chemical nature. Alcohol and water are completely miscible because of their chemical similarity, but some liquids are only partially miscible with others because of their chemical difference, e.g., benzene and water. Many gases are miscible with liquids to a greater or lesser extent, e.g., formaldehyde mixes readily with water; CO₂ is partially miscible with water, and oxygen only very slightly. Liquids that do not mix at all are said to be immiscible, as oil and water. The term solubility is often used synonymously with miscibility in reference to liquids, but it more properly applies to solids.
