What does it mean for a compound to be miscible in water?

Back

A compound is miscible in water if it can mix with water in any proportion without separating into two phases.

Front

What does it mean for a compound to be immiscible in water?

Back

A compound is immiscible in water if it does not mix with water and separates into distinct layers.
