"WebAs we add ethanol to water, the water hydrogen bonds strengthen with the water forming stiff clathrate cages around the ethanol molecules. However, as the volume ratio increases beyond 20%, a phase transition occurs where the water goes from its cage-like structure to forming hydrogen-bonded links between the ethanol molecules [ 3033 ].
