In chemistry, a miscible liquid/mixture is a mixture that completely combines to form a solution, these solutions do not produce a meniscus and create a completely new solution. Two materials are said to be miscible if they combine to form a homogeneous mixture. Immiscible refers to the inability to combine the two different liquids.
Miscible liquids:
Liquids that form together in a layer in all proportions mean that they are soluble in all quantities and are separated from the fractional distillation process. They are called miscible liquids.
immiscible liquids:
Liquids that do not mix and form different layers separated by a funnel are called immiscible liquids.
