Phase Diagrams of Binary Liquid Mixtures
Quick fact
Some binary mixtures, like water and triethylamine, have a lower critical solution temperature (LCST) – they become fully miscible when cooled below a specific point, opposite to the more common upper critical solution temperature (UCST).
Why this is interesting
You've seen oil and water separate, but did you know that some liquids mix completely only above a certain temperature? How do scientists predict when two liquids will form a single layer or separate into two?
