The natural liquid water exists in the form of molecular clusters, and the water molecules do not exist as a single _H2O due to the effect of hydrogen bonds. Instead, they can combine with each other to form water molecules. The angle between the OH bonds of water molecules is about 104.5°. When the water molecular group changes, the angle and length of the hydrogen bond change, resulting in a series of changes in the physical and chemical properties of water. The hydrogen bond angle of small molecular cluster water is less than 104.5°, the hydrogen bond angle of standard water molecule is less than 104.5°, and the hydrogen bond angle of large molecular cluster water is greater than 104.5°. The smallest water molecular cluster in nature is formed by the association of 6 water molecules, commonly known as hexagonal water or six-ring water. Small molecular cluster water has a hexagonal crystal structure, so it is commonly known as hexagonal water. The most typical in nature is glacier water and so on. Tap water is generally a water molecular cluster formed by the association of 13 water molecules; pure water is a water molecule cluster formed by the association of 30-40 water molecules; A water molecular cluster formed by the association of many water molecules. It is customary for us to call the water molecular clusters formed by the association of less than 10 water molecules as small molecular clusters, and the water molecular clusters formed by the association of more than 10 water molecules as macromolecular clusters. Negative ion water belongs to small molecular clusters. water. Because such water contains a lot of H atoms, the water quality is weakly alkaline and has anti-oxidation (reduction) effects. H atoms can promote cell activity and maintain reducing power, which is beneficial to human health.
