Answer:
The liquids water and glycerol are miscible in all proportions. Miscibility refers to the ability of two substances to mix and form a homogeneous solution. Water and glycerol can mix together in any ratio and form a single phase solution without separating into distinct layers. This is because both water and glycerol molecules have polar functional groups (hydroxyl groups) that can form hydrogen bonds with each other, allowing them to mix and dissolve completely.
