In this video, we will focus on Miscibility of liquids.
What is miscibility?
Miscibility is the property of two substances to mix completely to form a homogeneous mixture, which is, a solution.
Miscibility is most often applied to liquids but also applies to solids and gases. We will focus on miscibility of liquids in this video.
Miscible liquids dissolve in each other while immiscible liquids do not. For illustration, we have liquid A, which is yellow and liquid B, which is blue. When we add the 2 liquids together, they mix to form a green solution.
One very common example of miscible liquids is the mixture of ethanol and water. When we add these 2 liquids together, they mix to form one solution. A mixture of miscible liquids can be separated by fractional distillation.
When the liquids do not mix to form a solution, they are immiscible. When the 2 liquids are mixed together, they appear to form an emulsion. When we allow the mixture to rest, the emulsion eventually separates into distinct layers of liquids. One very common example of immiscible liquids is the mixture of oil and water. A mixture of immiscible liquids can be separated using a separating funnel.
