Definition - What does Miscibility mean?
Miscibility is the property of a substance that gets mixed in all proportions to form a homogeneous solution. It basically means how two or more liquids get completely dissolved in each other. The term is often applied to liquids but also to gases and solids. Ethanol and water are miscible as they get mixed in all proportions. When miscible liquids are mixed they show oily bands at first in bulk of the solution called striations. These striations disappear when the liquids are completely mixed.
Petropedia explains Miscibility
Miscibility of two or more materials is determined optically. When two or more miscible liquids are combined or mixed together, the output or the resulting liquid is clear. If the resulting liquid is cloudy then it is clear that the liquids are immiscible. It is important to determine the property of the liquids with proper attention and care as sometimes immiscible liquids give a clear resulting liquid which results in an incorrect determination that the liquids are miscible. Liquids are said to be immiscible if the attractions between the like molecules are stronger than the attractions between the mixed pairs.
