The property where two substances are not capable of combining is called?

The property of immiscibility is the inability of two substances to mix together to form a homogenous mixture. The parts are referred to as "immiscible." Fluids that do combine, however, are referred to as "miscible." An immiscible mixture's components will separate from one another. The more dense component will sink while the less dense fluid rises to the top. Water and oil are incompatible or immiscible liquids. Water and alcohol, on the other hand, mix entirely. Alcohol and water will combine in any ratio to create a homogenous solution.
