miscible

adj. can be mixed

Miscibility is a term in chemistry that refers to the property of liquids to mix in all proportions, forming a homogeneous solution. In principle, the term applies also to other phases (solids and gases), but the main focus on the solubility of one liquid in another. For example, water and ethanol are miscible in all proportions.
