When two liquids can be mixed together, they are “miscible”—they form something called a homogeneous solution, which means that you cannot distinguish the two liquids anymore. Immiscible solvents are incapable of mixing with another solvent and will separate out into a definite layer. Miscible liquids produce a clear liquid, while immiscible liquids yield a cloudy or layered mixture. Since by definition, immiscible liquids do not interact with each other. However, if the two liquids have the same color and similar indices of refraction, it may be difficult to see layers. Immiscible solids separate completely or else appear heterogeneous.
