Abstract This paper discusses the solidification characteristics of natural water, mineral water and purified water from the two aspects of supercooling degrees and freezing point depression. The conclusions are verified by experiments. It is clarified that colligative properties of dilute solutions and the destruction of the hydrogen bonds between water molecules due to hydration of ions (ion-dipole interactions) are the main reasons for changes of freezing points and supercooling degree of drinking water. This paper aims to provide a theoretical reference for the storage of drinking water at low temperatures, and help people correctly understand the solidification properties of water from multiple perspectives and promote their scientific cognition.
